I'd like to suggest a filter to the beatmap selection screen. It's currently possible to filter beatmaps by a collection. I'd like to be able to filter by beatmaps which are not in a specific collection. The possible usage for this feature would be: say you have a "Completed" collection where you put all beatmaps you've FC'd. This feature would allow you to filter out all of the beatmaps which are in the "Completed" collection and as a result the ones you don't want to play become invisible.
Another small suggestion from me is to add a "Not in any collection" category to the beatmap selection screen when using Group by Collection.
