Kanban quick filter dropdown by assignee

It would be very helpful to have a quick filter option by user so that we can quickly see a project's tasks on the same Kanban by a single user.

Currently a board administrator would need to configure the board's quick filters, add a single user which works for only a few users – not exactly elegant or scalable.

Ideally, it would be an auto-complete dropdown beside the quick filters allowing any user viewing a Kanban board to select a user and view tasks assigned to that user.

Thanks!
