Ability to rollup comments from linked records to another record. This would be particularly helpful when you may have projects or tasks assigned to a client, and you want to see all of the comments on those projects/tasks in the clients comments page.
This would help solve one of our main issues with Clickup which is comments and notes getting lost and being difficult to find. It would make the clients records comments (in my example) the single source of truth for all activity related to that client.
I imagine this would need to be a setting that you would turn on and off.
