Filtering subitems by status and person - STILL NOT POSSIBLE, SERIOUSLY?

I enter my board and see 30 subitems status DONE no way to filter them out.
Its is not efficient and it makes my work management very hard in complete contradiction to Monday’s marketing message “that it makes task management easy”
You’ve been saying for months now it’s under development, seriously.
Currently it’s not a “nice” to have feature it’s a basic feature.
