 - **Background daemon & service install** — `codeman web -d` runs the server detached with a pidfile, `~/.codeman/web.log`, and verified startup (it polls the server until it answers, so a port clash never reads as success); `codeman service install` writes a systemd user unit (Linux) or LaunchAgent (macOS) with your shell's PATH baked in, so an nvm or Homebrew `node`, `tmux` and `claude` are actually found. Secrets are never written into unit files
 - **Self-update** — git-clone installs under systemd/launchd update in place from **App Settings → System → Updates**: it detects the latest release, auto-stashes a dirty tree, and streams build progress across the service restart (npm installs report as non-updatable)
+- **Git status in the bottom bar** — off by default (**App Settings → Header & Panels → Bottom bar → Git status**, per device). A small indicator at the right of the bottom bar shows the active session's repository at a glance: `● 3` uncommitted files, `↑ 2` commits not pushed, `⚠` merge conflicts, `✓` all committed and pushed. Click it for a draggable window listing the staged, not-staged, untracked and conflicted files (grouped under collapsed folders, or as a flat list if you turn that setting off) and the unpushed commits; **click a file to see its diff** (new files as all additions, deleted files as all removals), with **Open file** to jump to the viewer. A folder that holds several projects gets one collapsible section per repository found up to two levels down, all collapsed until you open them. Read-only and offline (Codeman never fetches or changes the repo); not shown for Docker or remote sessions.
 - **Clone a GitHub repo as a case** — paste a repository URL into **Add Case → Clone Repo** and Codeman clones it into `~/codeman-cases/<name>` and registers it as a normal case, ready to run an agent in. It preflights the URL while you type (tells you whether it can be cloned anonymously and offers the repo's real branches and tags for the optional branch/tag field), fills the case name in from the URL, and lets you pick which CLI the Run button should use. Public repositories over `https://`; Codeman never collects or stores credentials
 - **Multi-CLI** — run **Claude Code**, **OpenCode**, **Codex**, **Antigravity**, **Gemini**, **Pi**, **Grok**, **DeepSeek Harness**, or **OMP** per session; env-var prefixes auto-gate (`CLAUDE_CODE_*` vs `OPENCODE_*` vs `CODEX_*` vs `ANTIGRAVITY_*` vs `GEMINI_*`/`GOOGLE_*` vs `PI_*` vs `GROK_*`/`XAI_*` vs `DSH_*`/`DEEPSEEK_*` vs `OMP_*`). See [`docs/opencode-integration.md`](docs/opencode-integration.md), [`docs/pi-integration.md`](docs/pi-integration.md), [`docs/grok-integration.md`](docs/grok-integration.md), [`docs/deepseek-integration.md`](docs/deepseek-integration.md) and [`docs/omp-integration.md`](docs/omp-integration.md)
 - **Custom model endpoints** _(new in 1.29.0, HTTP API for now)_ — point a session's CLI at any OpenAI-compatible endpoint instead of its native backend: a local llama.cpp, llama-swap, Ollama or vLLM box, or a cloud gateway such as Azure AI Foundry or OpenRouter. Save an endpoint once (`POST /api/model-endpoints`; its models are discovered from `/v1/models`), apply it to a session (`POST /api/sessions/:id/custom-model`), and the CLI restarts in place on that endpoint. Verified live for Claude, OpenCode, Pi, Grok and OMP; Codex, Gemini and DeepSeek have documented gaps, Antigravity has no mechanism. A toolbar picker is the follow-up.
