There needs to be a way to save and restore complex filters (similar to saved searches).

Simplified Example: I have a folder full of portraits and use a not-filter on "male" and "female" tags to see and tag all images that aren't tagged yet. I use this workflow for all my tags (like photo styles, clothing visible, hair color etc etc) and the filter combinations can get fairly complex. Now, if I add new photos I need to rebuild the filters again...

Suggestion: At the very top of the filters sidebar could be a text-input for a name, next to it a save button. Below a dropdown list with all saved filters, the default display could re d "load a saved filter" or "no saved filters". When loading one, the name should appear in the name input field above, so changes can be saved quickly or variations can be saved with only adding a letter/number to the original name.
This way there is not too much space wasted.
