If a filter-type has more than ten items, the filter selection changes from checkboxes, which can be changed very quickly, to a dropdown selection, which is (being polite) extremely slow to change.
Why?
Why not allow allow a project with 100 locations to add 5, or whatever, locations as checkboxes? (I know I can go into the location tab and select there, I’m making a general point. Though those filter icons should be checkboxes too, imo, but I digress.)
