Thanks for your feedback!
We’ve improved upon the Filter menu within a plan to give provide options for viewing certain tasks within a board.
We are planning to expand upon both the Filter menu options while exploring how to build search functionality that can fulfill the needs mentioned on this thread. Please comment if there’s anything in particular you’d like for our team to consider!
