Comment 18 for bug 494547

Ah, sorry for the duplicate. I actually searched for "save filter" and nothing came up, odd.

Anyway, is it really necessary to save it "per album"? I guess just a quick and easy way to save and load filter settings will get the job done in a similar manner?

Copy-Pasta of my 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.

Well, this means a two-click operation every time one want's to load an album with a filter... Sorry, I have no idea about programming, but maybe this is also a better solution in case there are performance issues with the per-album-setting: instead of saving all filter settings per album, just save a reference to a saved filter...
