I love the tracking that we're already providing in the GHPRI Copilot on My Behalf section. Here are some additional ideas:

• Status bar entry with a quick count of in-progress and completed Coding Agent (and maybe even local agent?) sessions
  • I'd love having this quick tracking visible to me as I do other work outside of GHPRI in the editor
  • I believe @joshspicer or @alexr00 added this previously - I'd love to discuss bringing it back
  • @jo-oikawa had mentioned yesterday that a quick count in the status bar would be useful
• Notification on chat history icon (i.e. blue dot indicating unread changes)
  • 
  • This maybe makes more sense if / when we have Coding Agent sessions in the same chat history
• Icon indicating availability of changes in chat session history
  • We don’t currently have an icon to differentiate sessions from history that have code changes. When navigating previous chat sessions, it's not clear which ones resulted in code changes:
  • 
  • This also maybe makes more sense if / when we have Coding Agent sessions in the same chat history, though local agent sessions can also produce code changes

cc @rebornix since these several of these were your ideas and/or we discussed them.

I think this is related to but different from microsoft/vscode-pull-request-github#7148.
