Create a way to save frequently used filters from the quick filter view.
Would this be in addition to saving your settings as a view?
Typically I just save my filter, and other display settings, as a view I can pick from the top of the board. Unless you’re talking about a very large number of filters.
It could be on a widget or a view. Instead of having to save numerous different versions of a widget or view to zero in on different teams, for example, you could save these “team filters” so you could apply them in different widgets or views as needed.
