A session whose agent is working showed only an accent dot at the end of its sidebar row. Its name now shimmers the same way the busy line above the prompt box does. The dot stays, so working, waiting on you and finished-while-away still read apart.

While it shimmers, a long name is clipped rather than ellipsed, as on subagent cards. The PR could not show the sweep in a still capture, and found the shimmer was not visibly sweeping anywhere; that was fixed in the follow-up.

In the app

Before: a working session shows the dot, and its name is cut off with an ellipsis.

After: the working session's name is drawn by the shimmer, so it is clipped instead of ellipsed.
