Quarters 0.4.0

The first release published as a signed, notarized app, installable with
brew install --cask amithgc/tap/quarters (and brew install amithgc/tap/quarters-server on Linux). Quarters now runs eight coding
agents, not only Claude Code; everything since 0.3.0 is below.

• Images the agent sends. On a phone, a chat reply that names an image
  file (PNG, JPEG, GIF, WebP) shows the picture under it; a tap opens it
  full screen, and a missing file says so. In any terminal (the Mac, a
  tablet, a phone's terminal view, every agent and shells), an image path
  is a link: hover to preview it, click to open it full screen (Esc
  closes). The Mac reads only a path the tab itself showed (in the agent's
  conversation or printed in the terminal), checks the file really is an
  image (not just named like one) and caps it at 15 MB.

• Phones: one session view for every coding agent. Claude Code, Codex,
  OpenCode and the rest all get the message card below their transcript
  (↑ send, ■ stop with the agent's own interrupt key, the tab tools) and
  the key bar while typing. The card no longer lies over Claude's input
  box: it sits below the terminal, which fits the space above it. Claude
  Code keeps its chat view (▤/💬, remembered per agent); agents whose menus
  can't be tapped always get the key bar's arrows. Shells stay plain
  terminals; tablets are unchanged.

• Devin (Cognition's devin CLI) is one of the coding agents: continue is
  --continue, skipping permission prompts is --permission-mode bypass.

• The side panel lists the open project's automations: run or restart,
  stop, edit, delete, and ＋ new. It also has the project's coding agent
  (Agent): pick one from the menu and Apply, on the Mac. In a project that
  runs another agent, the panel leaves out Claude Code's plan, Remote
  Control, session stats, tools, skills and MCP servers. Antigravity
  projects show Antigravity's plan and each model's quota instead, read
  from the Antigravity IDE on the same Mac while it's open (a local,
  unofficial interface; nothing leaves the Mac).

• Other coding agents besides Claude Code: Codex, Gemini CLI, Antigravity,
  OpenCode, GitHub Copilot CLI, Devin and Aider. Choose the default in Settings →
  Coding agent, and per project in the side panel or ✎ ("harness" in
  config.json). New
  tabs, continue and yolo use each agent's own command and switches; ones
  not installed are marked, and starting one says where to get it. Stats,
  past conversations, the phone's chat view and Remote Control stay
  Claude Code's; other agents are plain terminals there.

• Tablets type straight into the terminal (Claude's own input box), like
  the Mac: no second text field; the key bar comes up while typing. Shell
  tabs have no text field on any touch screen.

• On phones, shell and automation tabs are plain terminals: no message
  box, you type straight in, the tab bar (with the tools) is always shown,
  and the key bar comes up while typing.

• On Android over the home network's plain HTTP, the sign-in page shows how
  to let Chrome install the app (it installs only from secure addresses;
  Chrome's per-address setting is enough, no HTTPS needed).

• Linux: the remote-access server alone (no window) builds for Linux
  (make server, amd64 and arm64, no dependencies) and runs from the
  command line: --set-password, --pair, --devices, --remove-device.
  It reads Claude Code's login from ~/.claude/.credentials.json, keeps
  the machine awake with systemd-inhibit and opens links with xdg-open;
  home-network addresses include Linux port names (eth0, enp3s0, wlan0…).
  CI builds and tests it on Linux.

• Without $SHELL (a service, a container), shells use the first of zsh,
  bash and sh the machine has.

• Keyboard shortcuts dialog on the Mac: Help → Keyboard Shortcuts (⌘/),
  or "⌘/ shortcuts" in the bottom bar.

• The Claude Remote Control switch is about the Claude session in view:
  on when Claude Code has it connected (read from Claude Code's own list,
  whoever turned it on), and flipping it runs /remote-control in that
  session. "Start new Claude tabs with it" is a checkbox below. The
  project-list mark follows the same live state.

• End this Claude session in the side panel (⋯ on a phone), for the tab
  you're looking at; it asks first.

• iPhone home-screen app: the status bar is opaque (black), so the page
  reaches the bottom of the screen; with the translucent bar iOS cut it 62
  points short (re-add the app to the home screen to pick this up). The
  page follows the visual viewport, so the message box stays above the
  keyboard.

• The phone chat follows the log Claude Code actually writes, and no longer
  mistakes ❯ lines from earlier prompts for a menu.

• Project list: a little room in git counts (● 6, ↑ 3), and a broadcast
  icon on projects with a session under Claude Remote Control.

• Chat view on phones: a Claude tab reads like the Claude app. The
  conversation comes from Claude Code's own log: your messages as bubbles,
  Claude's replies formatted, tool use folded into rows such as "Ran a
  command, edited a file ›" (tap for commands, results and diffs), and
  "✻ Working…" while it works. Claude's menus and questions become
  buttons, the send button stops Claude while it works, and ▤ switches to
  the terminal.

• Phones look and feel like the Claude app: a round ☰, a centred title
  with what the tab is doing, a status pill with ⋯ for Quarters' extras
  (plan, session, tokens, git, servers, MCP, skills), tabs as pills, and a
  message card with the tools (new tab, shell, automations, prompts,
  conversations, worktrees) and a round send button.

• An ACTIVE section at the top of the project list shows the projects
  with open sessions, working ones first.

• Phones type into a real text field (autocorrect, dictation, selection,
  a backspace that repeats) and send with ↑ or return; backspace in an
  empty field deletes in Claude's input. Tapping the terminal opens it.

• Swipe a terminal to scroll its history on touch screens, with momentum.

• Claude Remote Control toggle in the side panel: new Claude tabs start
  with claude --remote-control <project>, so they can also be continued
  from claude.ai/code and the Claude app.

• Phone-sized interface on phones: 16px text, a bigger title bar (19px
  project name), taller tabs with 44pt buttons, roomier project rows in the
  drawer, and the working/waiting counts as just ● and ◐ with a number.

• On phones and tablets, Claude Code's menus (trust this folder, allow a
  tool…) are answered by tapping: tap an option to highlight it, tap it
  again to choose it. No arrow keys needed.

• Phones show the terminal at 15px (was 11px), closer to a chat app, and
  pinching a terminal with two fingers changes the text size.

• Each window works on its own. A Claude tab in a window you're not using
  pauses ("In use on another device") instead of following the other
  window's size and keystrokes; clicking or typing there takes it back,
  and Claude reprints the whole conversation at that window's size.
  Shell and automation tabs still mirror live, at the size of the window
  in use.

• The phone's key bar (esc, tab, ⇧tab, ctrl, arrows) shows only while you
  type in a terminal, and can be switched off in Settings (Phone key bar).

• Claude Code's ⏺, ✔, ⏸, ✳, ⚡… no longer turn into wide colour emoji on
  phones: a small bundled font (tools/symbols) draws them one cell wide.

• The welcome screen lists the projects with open sessions (working or
  waiting for you); tap one to open it.

• A session taken over by a window of another width (phone ↔ Mac) is
  redrawn cleanly instead of leaving copies of Claude's input box behind.
  The phone keyboard no longer shows the AutoFill bar over the terminal.

• Password sign-in: a username and password, set on the Mac, for
  browsers that can't use a passkey. Stored as an argon2id hash, with the
  same lockouts as passkeys. Quarters --set-password <name> sets it
  without a window.

• Home network: Remote Access can also open Quarters at the Mac's
  address on your Wi-Fi (http://192.168.x.x:8421), with a QR code, for
  private addresses only.

• The public URL in Remote Access is optional: without one, the server runs
  at http://localhost:8421, for this Mac or an SSH tunnel.

• Opening http://127.0.0.1:<port> without a public URL goes to
  http://localhost:<port>, where passkeys work (it used to fail with
  "cross-origin request blocked").

• The title bar shows the date and a 12-hour clock; the remote pill is always
  there (greyed out while the server is stopped) and its dot pulses while
  it runs.

• Dialogs open in the middle of the window (Settings used to sit at the
  bottom).
