Problem or use case

Thread titles in the sidebar are visually truncated to fit the available width. When a title is longer than the sidebar row, there is no hover affordance to reveal the full name, which makes it harder to see full thread names, and to distinguish similarly named threads without opening them.

Proposed solution

Show the full thread title in a tooltip when hovering the truncated thread name in the sidebar.

Use the app’s existing styled tooltip component so the interaction matches other hover help in the UI.

Why this matters

This will make it easier to see full thread names, and to distinguish similarly named threads without opening them.

Smallest useful scope

Add a hover tooltip for the thread title in the sidebar thread row only.

Alternatives considered

• Workaround: Expanding the row, seeing the the chat header after opening the thread.
• Another solution I tried: Native browser title tooltip: works, but is visually inconsistent with the rest of the app’s styled tooltips.
