you know on the top right where you got your preset options to sort your beatmaps by collections, recently played, artist, etc. etc.? I think it'd be nice to be able to make custom presets. For example you could make a tab for grouping by ranked status and sorting by difficulty and another one grouping by date added and sorting by difficulty, but still have your collections at the ready. Would probably make a great supporter add-on(as in it's not totally game changing but definitely nice to have).
