 - **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. **Fetch** in that window's header runs `git fetch` for the repositories it lists, on your click or on an interval you turn on (**App Settings → Bottom bar**, off by default; **Session Options → Git** overrides both the switch and the interval per session). Sessions open on the same folder share one run and each sees its result. Apart from that fetch Codeman never fetches or changes the repo, so "behind" is as of the last fetch; 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
 - **Create a case in a custom folder** — tick **Create in a custom folder** in **Add Case → Create New**, pick a parent folder (Browse included) and a name, and Codeman scaffolds the new case there instead of `~/codeman-cases`. The target must be a new or empty folder; system directories, your home folder itself, credential trees such as `~/.ssh`, and Codeman's own data folder are refused. Admin only in multi-user mode.
+- **Open a tmux session you started by hand**: a tmux session started outside Codeman shows up on the home screen, on this machine automatically and in your Docker cases' containers or on your saved SSH hosts when you scan for them. One click opens it as a tab. Closing the tab only detaches, and Codeman will not respawn or relaunch an agent it did not start. See [Opened outside Codeman](docs/wiki/The-Dashboard.md#opened-outside-codeman).
 - **Multi-CLI** — run **Claude Code**, **OpenCode**, **Codex**, **Antigravity**, **Gemini**, **Pi**, **Grok**, **DeepSeek Harness**, **OMP**, or **GitHub Copilot CLI** 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_*` vs `COPILOT_*`). 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) [`docs/omp-integration.md`](docs/omp-integration.md) and [`docs/copilot-integration.md`](docs/copilot-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. See [`docs/custom-model-endpoints.md`](docs/custom-model-endpoints.md)
 - **Web tabs** — open Grafana, Uptime Kuma, a Vite dev server or any dashboard URL as a tab beside your sessions (Run dropdown → **Web / URL** → **Add URL**). Dashboards are proxied through Codeman's own origin, so an `http://` target works from a phone over HTTPS and through the tunnel, single-page apps route on their own paths, and a frame that reloads recovers itself. A `localhost` link an agent prints opens as a web tab automatically. See [`docs/web-tabs.md`](docs/web-tabs.md)

 - **底栏里的 Git 状态**：默认关闭（**App Settings → Header & Panels → Bottom bar → Git status**，按设备生效）。底栏右侧的一个小指示器让你一眼看清当前会话所在仓库的状态：`● 3` 表示未提交的文件，`↑ 2` 表示未推送的提交，`⚠` 表示合并冲突，`✓` 表示全部已提交并推送。点击它会打开一个可拖动的窗口，列出已暂存、未暂存、未跟踪和有冲突的文件（按折叠的文件夹分组，关掉该设置则显示为平铺列表）以及未推送的提交；**点击文件即可查看它的 diff**（新文件全部显示为新增，已删除的文件全部显示为删除），**Open file** 可直接跳到查看器。一个包含多个项目的文件夹，会为向下两层内找到的每个仓库各给一个可折叠分区，打开之前全部折叠。只读且离线（Codeman 绝不 fetch，也绝不改动仓库）；Docker 和远程会话不显示
 - **把 GitHub 仓库克隆成 case** —— 在 **Add Case → Clone Repo** 里粘贴一个仓库 URL，Codeman 会把它克隆到 `~/codeman-cases/<name>` 并注册为普通 case，随时可以跑智能体。输入时它会预检 URL（告诉你能否匿名克隆，并为可选的分支/标签字段提供仓库真实的分支与标签），从 URL 里填好 case 名，还让你选 Run 按钮该用哪个 CLI。支持 `https://` 的公开仓库；Codeman 绝不收集或保存凭据
 - **在自定义文件夹里创建 case**：在 **Add Case → Create New** 里勾选 **Create in a custom folder**，选一个父文件夹（可用 Browse 浏览）和一个名字，Codeman 就会在那里而不是 `~/codeman-cases` 里搭建新 case。目标必须是一个新的或空的文件夹；系统目录、你的主目录本身、`~/.ssh` 这类凭据目录，以及 Codeman 自己的数据目录都会被拒绝。多用户模式下仅管理员可用
+- **打开你手动启动的 tmux 会话**：在 Codeman 之外启动的 tmux 会话会出现在主屏幕上：本机的会自动列出，Docker case 容器内和已保存 SSH 主机上的会在你扫描时列出。点一下即可作为标签页打开。关闭标签页只会分离，Codeman 不会重生或重启并非由它启动的智能体。详见 [Opened outside Codeman](docs/wiki/The-Dashboard.md#opened-outside-codeman)。
 - **多 CLI** —— 每个会话可选 **Claude Code**、**OpenCode**、**Codex**、**Antigravity**、**Gemini**、**Pi**、**Grok**、**DeepSeek Harness**、**OMP** 或 **GitHub Copilot CLI**；环境变量前缀自动隔离（`CLAUDE_CODE_*`、`OPENCODE_*`、`CODEX_*`、`ANTIGRAVITY_*`、`GEMINI_*`/`GOOGLE_*`、`PI_*`、`GROK_*`/`XAI_*`、`DSH_*`/`DEEPSEEK_*`、`OMP_*` 与 `COPILOT_*`）。详见 [`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)、[`docs/omp-integration.md`](docs/omp-integration.md) 与 [`docs/copilot-integration.md`](docs/copilot-integration.md)
 - **自定义模型端点**（1.29.0 新增，目前仅 HTTP API）—— 让某个会话的 CLI 指向任意 OpenAI 兼容端点，而不是它自己的官方后端：本地的 llama.cpp、llama-swap、Ollama 或 vLLM 机器，也可以是 Azure AI Foundry、OpenRouter 这类云端网关。端点只需保存一次（`POST /api/model-endpoints`，模型列表从它的 `/v1/models` 自动发现），再应用到会话（`POST /api/sessions/:id/custom-model`），CLI 就会在原地重启并接上该端点。Claude、OpenCode、Pi、Grok 与 OMP 已实测通过；Codex、Gemini 与 DeepSeek 存在已记录的缺口，Antigravity 没有可用机制。工具栏选择器是下一步。详见 [`docs/custom-model-endpoints.md`](docs/custom-model-endpoints.md)
 - **Web 标签页** —— 把 Grafana、Uptime Kuma、一个 Vite 开发服务器或任何仪表盘 URL 作为标签页打开在会话旁边（Run 下拉菜单 → **Web / URL** → **Add URL**）。仪表盘通过 Codeman 自己的源代理，因此 `http://` 目标在手机上走 HTTPS 也能用、走隧道也能用；单页应用能在自己的路径上正常路由，页面自己重载后也能自行恢复。智能体打印出的 `localhost` 链接会自动以 Web 标签页打开。详见 [`docs/web-tabs.md`](docs/web-tabs.md)
