First of all, I've got to say how impressed my team and I are by this software and by the overall responsiveness of the ClickUp team. Keep it up guys!
I've implemented ClickUp across a 50 person team and there's one missing feature which should be pretty straight forward to implement: an "assigner" or "created by" field.
The same way box view helps you look at tasks in terms of team members, this additional field in list view with a sorting & filtering option would help you complete tasks for a certain manager or team member (before a meeting perhaps.)
It would also help with reporting to see who's creating work vs. who's completing work.
Let me know if this would be of any value, or if I'm missing something that already exists.
