The right-hand column had three widths, each picked where it was written: text fields 260, sliders 240, dropdowns 180. Every row still ended on the same right edge, so on one page the difference read as controls aligned carelessly rather than as controls of different kinds -- and moving between Appearance and Terminal, where the mix differs, the column visibly changed width. FIELD_W is the one number now, at 260, the widest of the three because it is the one with a requirement behind it: a font name or a shell path has to fit untruncated. The Program row's shell picker was a ghost button, which fills a rounded rectangle while its menu is open, sized by hit_target to the 24px accessibility floor -- exactly the field's inner height, so that fill met the border top and bottom and looked like a patch stuck over the field's right end. It now draws with no fill in any state, the way Select draws its own chevron. Its menu was min_w(200) anchored TopRight on a chevron that sits inside the field, so it hung off the field's right half with its left edge 110px in from the field's own; it is now as wide as the field it drops out of.
tty7
A terminal workbench: persistent sessions, remote work, agents.

Why
A background server owns your shells and panes — not the window. Everything below follows from that.
- Performance — ~2× the throughput of Alacritty, Ghostty, or Kitty (benchmarks)
- Persistent sessions — quit or reboot; your shells and supported agent sessions keep running, no tmux
- Agent-aware — Claude Code, Codex & co.: status, notifications, and git context for every repo at once
- Scriptable by agents — one agent opens a pane for another, hands off a task, waits, and reads the result, with or without the GUI running
- Editor-grade input — suggestions, completion, highlighting, history search, with no plugin to install
- Remote development — files, repos, panes, and git data stay on the remote machine, over a native SSH stack
- Git beside the terminal — source control, diffs, and worktrees without leaving the window

| Git | panel follows the focused pane · stage, commit, amend, branch, push, stash · side-by-side or unified diffs · commit graph with cherry-pick, revert, and reset · a new worktree opens its own tab |
Supported agents
Detection is free: brand avatar, branch + diff, tab title.
Status takes one click under Settings → Agents to install that agent's hook,
and brings the status dot, notifications, the tray icon, tty7 wait, and resume
after a reboot. Fork needs both — the agent's own fork command, and the hook
that tells tty7 which session to fork.

None of them are wrapped or proxied — the agent you start is the agent you get,
in a normal PTY, with its own interface. An agent launched through a wrapper
script can be mapped to one by name with agent_commands in config.json.
