   Thanks for the suggestion! You're asking for a Fork button next to Revert and Copy on each user message in the session timeline. Clicking it would fork the session at that message and open the new session.

   A couple of notes from looking at the current code:

   • /fork already opens a "Fork from message" picker where you choose the user message to fork from (packages/app/src/session/commands/fork-dialog.tsx). So the underlying fork-at-message behaviour exists; what's missing is a per-message shortcut.
   • There's no reserved fork action right now. SessionUserActions in packages/session-ui/src/actions.ts only has openAttachment, revert and pending, and message-part.tsx no longer exists. Wiring this up would mean adding the action there and connecting it the same way the fork dialog does.

   Maintainers will consider it. Related issues:

   This was fixed by #58865. That PR merged into the beta branch, so GitHub didn't close this issue automatically. The fix will be in the next release. Closing as completed.
