The filter feature is awesome, including the list of "Other filters" that make it easy to get to what I'm looking for. Unfortunately, there doesn't appear to be a way to save a filter or to even bookmark the currently selected filters. Being able to save a filter would make it much easier to implement workflows, like using tags to indicate and quickly find which stories need designs, which stories are ready for sprint planning, etc. 

A couple additional thoughts around filters: 

• Click on a tag within a card and have that apply a tag filter without the need to open the filter dialog. 
• When in filter mode, click ESC (or a filter banner) to exit out of filter mode without having to re-open the filter dialog and scroll to and click the "Clear Filters" button.
