…n view Redesign SendMessagePopup from a small centered popup to a full-screen 3-panel layout (request/response/history) matching the HTTP Probe pattern. InOut responses now show exchange headers and scrollable body with pretty print toggle. Adds send history with replay support. Extract shared form utilities (HeaderEntry, handleTextInput, renderLabel, handlePaste) into FormHelper to eliminate duplication between SendMessagePopup and HttpTab. Add Clear + padding to both views for visual separation. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

…nspect badge count Remove redundant 1-9/1-0/1-2 tab switching hints from footer across all tabs since the tab bar at the top already shows available tabs. Fix the Inspect tab badge to show count of distinct exchanges instead of individual processing steps. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Add a Reset Screen action to the F2 actions menu (Diagnostics group) that clears the terminal and resets TamboUI buffers, forcing a full redraw. Useful when the screen gets garbled from external interference. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

…mples repo Extend the sync-example-catalog Maven profile to also download source files for all bundled examples from apache/camel-jbang-examples. Add examples/**/* excludes to both RAT and mycila license plugins so synced files don't need license headers. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Fix missing Reset Screen entry in visual menu list, use dynamic visualActionCount instead of hardcoded sums, and use 🧹 emoji instead of 🖥️ which has a variation selector causing width mismatch. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Shrink the route diagram example to fit more easily in the help overlay viewport, fix when[cond] box alignment, and add scroll hint until TamboUI supports partial code block rendering. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

- Move Classpath from F2 action popup to its own tab in the More menu - Delete ClasspathPopup, create ClasspathTab implementing MonitorTab - Replace fragile int action constants with Action enum in ActionsPopup - Fix GROUP_SIZES after classpath removal (4,5,5 -> 4,4,5) - Rename "Show Documentation" to "Show Integration Doc" - Clear full area in doc viewer to prevent background bleed-through - Remove unnecessary F5 reload from ClasspathTab (classpath is static) - Add PgUp/PgDn navigation to ClasspathTab - Fix diagram flicker: skip loading placeholder on metric refreshes - Preserve diagram scroll position across F5 and metric refreshes - Bump screenshot notification from 3s to 5s Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Enable auto-refresh for both text and image diagrams when metrics are on, removing the need for manual F5. Use quiet reload for the m toggle to avoid flicker when switching metrics on/off. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

…abled The drawArrowFromMerge method read stats unconditionally, causing the last node counter to appear even with metrics off. Gate it behind the metrics flag like drawArrow already does. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
