Thank you Clickup! So happy to see Clickup in Teams. Having experimented for a bit, the below would be my top picks for next improvements).

Nest activity feed (if more than one change is made on the same ticket, group into one activity - right now if i change an assignee and status and add a comment, i get two activities, which floods my activity notifications)

Change banner content (to include more detail on the ticket, instead of the generic banner - even the ticket title would help)

Allow ticket status changes and assignee changes from within Teams.
