WebUI interface implemented, WIFI needs to be active (http://IP), usr: admin / pass: BLE-code

Changed / Improved

• WebUI message navigation and thread behavior refined
  • Bottom tab presses now always return to the selected tab's root view, reducing stale nested-state confusion
  • Message list navigation arrows are now visually consistent
  • Channel/DM reply action labels now use "RPL" and signal badges display compact RSSI/SNR formatting
• WebUI message detail page redesigned for faster diagnostics
  • Message detail now surfaces key delivery and route context first, including clearer hops vs repeats emphasis based on message direction
  • Metadata and raw transport details remain available in a more structured layout
• WebUI channel management cleanup
  • The extra key-format helper line was removed from the Regions section to reduce visual noise
• On-screen light color scheme readability overhaul
  • Light mode now uses a bright white base with stronger contrast treatment for controls, improving legibility in heavy sunlight
  • Buttons across the on-device UI were visually unified for outdoor use with clearer borders and higher-contrast label rendering
  • Badge and accent colors were adjusted in light mode so critical status indicators remain easy to distinguish on bright backgrounds
  • Contact list rows were tuned for light mode readability with clearer row separation and easier-to-read text treatment
• MAP marker and badge consistency improvements
  • Map device hash badges now follow each device's advertised hash width (1-byte, 2-byte, or 3-byte) instead of the local multi-byte hash preference
  • Map device badge colors now match device type coloring used in contact badges (for example SVR and RPT), improving consistency across the UI
• Management log readability improved — long entries wrap to available width
• More consistent device colors across the interface
• Channel and DM views stay responsive while browsing larger histories
• CrowPanel 7 list readability, alignment, and text size improved across all screens
• Build stability follow-up — stale platform overrides removed; all targets revalidated
• Contact route badges correctly decode 1-, 2-, and 3-byte multihash paths
• DM route hints now survive device restart
• Manual location setting now available in MCTerm via GPS menu
  • WebUI displays 3-state mode selector: Off (no location), GPS (real-time), Manual (fixed coordinates)
  • Set manual location via text input fields for latitude, longitude, altitude
  • Set location from map view using "Use Map Center" button
  • Clear location via "Clear Loc" button
  • Uses existing firmware protocol (CMD_SET_ADVERT_LATLON) — no companion app protocol changes
  • Matches official companion app behavior for manual location configuration
  • HOWTO: Open Mgmt -> GPS. - Go to Manual Location. - Tap Edit on Manual Lat, enter latitude, confirm. - Tap Edit on Manual Lon, enter longitude, confirm. - Tap Edit on Manual Alt, enter altitude in meters, confirm. - Set Advert Location to Manual (cycle button until it shows Manual), so adverts use your manual coordinates.

Added

• Message detail can now jump directly to map route visualization
  • Selecting the hop count in message detail opens the map and overlays the known hop path as connected lines between devices
• T-Deck Plus: Alt+S and SYM key now cycle input modes
  • Pressing Alt+S on the hardware keyboard cycles through all four input modes: uppercase, lowercase, SYM1, and SYM2
  • Pressing the standalone SYM key jumps directly to SYM1; pressing again advances to SYM2 and then back to normal
  • The modifier detection was unreliable due to a hardware quirk; it now reads directly from the keyboard matrix for accurate results
• T-Deck Plus: SYM1 and SYM2 touch buttons added to the message send bar
  • While composing a message, two buttons labelled SYM1 and SYM2 are now visible at the bottom of the input panel, allowing direct access to symbol input modes without using the hardware keyboard shortcut
  • In symbol mode the full on-screen symbol picker is shown; the trackball navigates the grid and pressing the trackball button inserts the selected character
  • Alt+S now jumps straight to SYM1 from any normal input mode and stepping it again moves to SYM2 then back
• WebUI: message hash codes replaced with contact names
  • Hop-path hash codes (the short bracketed hex codes like [A3], [B2F1] etc.) in channel and DM messages are now automatically replaced by the matching contact name from your contact list, shown in that contact's color
  • If no contact matches a hash code, it is shown dimmed so it remains readable but visually de-emphasised
  • Can be turned off in Mgmt → Messages → Replace HashCodes
  • On-device and WebUI naming behavior now stays aligned through the shared "Replace HashCodes" setting
• Default flood scope: persistent per-device send scope
  • A default flood scope can now be stored in device preferences and applied automatically to all outgoing flood messages when no other scope is active
  • Configurable from the browser node settings panel and the command-line interface
• Map: network tile load reliability improvements for hosted-WiFi targets
  • Map tile loading is more reliable on devices that use a separate co-processor for WiFi bridging; timeouts are tighter and tile requests no longer collide with background state updates
• WebUI: full-featured browser interface via WebSocket
  • Browser-hosted companion UI served directly from the device over WiFi — no app install required
  • All screens (contacts, channels, DMs, map, management, repeater admin) update in real time via WebSocket without page reloads
  • Repeater admin includes live device status readout (battery, uptime, RSSI/SNR, airtime, packet counters) bridged from the binary protocol -> WIP
  • Transient status messages (e.g. sent confirmations, error notices) appear briefly in the header, matching the on-device display behavior
  • Repeater status and clock refresh operations run quietly behind a single progress indicator instead of spamming the channel with individual commands
• Mgmt/Channels: region scope support with per-channel assignment
  • Region scope definitions added using MeshCore's flood-scope system, with one scope assignable per channel
• Mgmt/Channels: new Regions and Scope overlay pickers
  • The Regions section opens a dedicated overlay listing all defined scopes; each region can be toggled between allow-flood and deny-flood modes
  • Channel rows open a scope picker directly; the currently assigned scope name is shown on the channel row button
• Mgmt/Date-Time: NTP timezone and server labels fully visible on CrowPanel 7
• Mgmt/WiFi: extended network diagnostics and static IP support
  • WiFi management shows subnet, gateway, and both DNS server addresses; a new mode control switches between DHCP and static addressing
• GUI: contact list reachability badges condensed
  • Direct-link badge is now "D" (green); flood-route badge is now "F" (blue)
• GUI: status-bar clock with quick Date/Time access
  • A live clock is always shown in the status bar; tapping it jumps to Mgmt → Date/Time
• GUI: contact list badge reordering and new address-width badge
  • Badge order from right: address-width, type, route, last-heard, favourite, GPS, unread mail
• GUI: unread message indicators moved to Msgs tab button
  • The Msgs tab shows a white envelope for unread channel messages and a red envelope for unread DMs
• Duty-cycle display shows configured budget instead of lifetime airtime ratio
• Msgs: QuickR1 and QuickR2 custom reply presets
  • Quick reply templates accept both (VAR) and [VAR] syntax on touch and physical keyboards
  • Supported variables are HP (hop path), HC (hop count), SNR (signal-to-noise ratio), and RSSI (received signal strength)
  • Both quick reply slots are editable in Mgmt → Messages; pre-filled with useful defaults on first boot
  • Reply buttons expand hop path, hop count, SNR, and RSSI from the selected message
• Mgmt/Global: MCTerm firmware information section added
• Identity key management added across device UI and WebUI
  • The management interface now exposes identity details directly on-device, including private-key visibility and guided save/load operations with SD card files
  • Private keys can now be set manually, imported from SD card identity files, and applied without companion app tooling
  • The browser interface now includes a full import/export flow with direct key export, identity bundle export, file-based import, and SD card save/load actions

Fixed

• WebUI "Load older messages" indicator now appears only when older pages are actually available
  • The action no longer appears in states where there is nothing older to fetch, making history availability clearer
• Message history pruning now retains valid messages when the device clock is far ahead of message timestamps
  • A faulty or unsynced real-time clock could cause all stored messages to appear expired and get pruned on boot; messages are now preserved whenever the clock has not yet been corrected
• Message ring counters stay accurate after a history prune pass
  • Stored message counts shown in the UI and diagnostic views could drift from the actual ring contents after pruning; they now update correctly
• DM details no longer show fake hop paths for unreachable flood-routed messages
  • Repeater forwards are now shown in the repeats section, and unknown routes no longer display an invalid high hop count
• DM delivery status now clearly follows the Mark Delivered Faster setting
  • If Mark Delivered Faster is enabled, your reported behavior still happens by design.
  • If Mark Delivered Faster is disabled, behavior matches your expected ACK-only Delivered semantics.
• Room server messages now show the original poster name
  • Posts relayed through a room server are now attributed to the participant who sent them instead of showing the room server name as the sender
• WebUI: character counter no longer retains the previous count after a message is sent
• WebUI: opening a channel with unread messages now marks them as read immediately
• WebUI: management screen fields and dropdowns no longer lose their value mid-edit when a background status update arrives
• WebUI: saving a management setting now shows the confirmation status briefly instead of being immediately overwritten by a loading indicator
• WebUI: GPS status badge added to the header — shows green when a fix is acquired, gray when searching or disabled, and hidden when GPS is not available on the device; hovering shows the exact GPS status
• WebUI: route, signal, and action buttons in message rows now show descriptive tooltips on hover
• WebUI: channel view header buttons (back, scope, delete) now show descriptive tooltips on hover
• Channel region scope was never actually applied when sending
  • A protocol framing mistake caused the flood-scope command to silently fail on every attempt; fixed so the scope is reliably applied before each send
• SD message store: all messages except the last were lost on reboot before compaction
  • Journal was opened in truncate mode instead of append mode; fixed so all messages accumulate correctly between compaction cycles
• SD message store: history older than the last ~48 messages was silently discarded on compaction
  • Idle compaction wrote only the in-memory ring back to the snapshot then cleared the journal, permanently losing older messages regardless of the retention setting; compaction now merges the full journal and existing snapshot so all retained messages survive
• SD message store: configured message retention days reverted to 15 after every reboot
  • A byte-order mismatch between the save and load paths caused the setting to be read back from an unrelated field; value now survives reboots correctly
• SD message store: history could fail to compact after leaving a per-channel filtered view
  • The pending-compaction flag was cleared when the channel filter blocked compaction; the retry was never attempted after returning to the combined view
• Region and scope definitions now survive device reboot
  • Definitions and per-channel assignments were RAM-only; now saved to flash immediately on any change
• CrowPanel 7 hosted map downloads recover after connection errors
• CrowPanel 7 time sync no longer reports false NTP success from the boot clock
• Peer and GPS time sync rejects implausible timestamps
• Mgmt/WiFi: switching from static IP back to DHCP could keep stale lease values
• Mgmt/WiFi profiles now show saved password state before SSID is set
  • Entering a password before SSID no longer shows "(not set)" in the management overview; both on-device and browser views now show that a password is stored
• GUI: Date/Time set dialog used wrong timezone
• GUI: contact data could become corrupted after malformed updates or bad stored names
• Contacts list Last Heard badge now avoids unitless large values
  • Invalid or ambiguous timestamps that previously showed confusing numbers now display as N/A
• GUI: long-tap copy in message detail could paste only a partial line
• Management log truncation regression fixed
• Mgmt/Log timestamps no longer oscillate between adjacent minutes
  • Log entry timestamps now remain stable once captured instead of flipping between two minute values
• Repeater login set the repeater clock to a near-zero timestamp
• Mgmt/Contacts: AutoAdd Max Hops display was off by one
• Map: repeater info popup did not open when tapping markers at higher zoom levels
  • Marker tap detection now stays reliable across zoom levels, so repeater details open correctly
• Map marker contact opening no longer depends on tap timing
  • Tapping a marker shows its info box, and tapping the info box opens contact detail for a more reliable interaction
• Mgmt/Advert scan: single-attempt scans missed nearby repeaters
• Mgmt/Advert Scan Rpts now handles prefix-only repeater matches correctly
  • Known repeaters discovered by scan now show their saved contact names and open contact detail on row tap
  • When only a short prefix is known and multiple contacts share it, the UI now explains the ambiguity instead of showing a generic key-missing message
  • Repeaters that are not yet in Contacts can now be added directly when a unique full identity can be resolved from recent scan results
• Device: message read state now saved to storage when scrolling through messages on-device
  • Previously read state was lost on reboot; now persisted immediately and browser unread counters stay in sync
• Elecrow CrowPanel 3.5: soft-SPI SD shim build fixed
• WebUI: "Jump to latest" button now stays visible while scrolling up in message history
  • The button was placed at the end of the message list and scrolled out of view when reading older messages; it now sticks to the bottom of the visible conversation area so it is always reachable without scrolling back down first
