Clear enough. There is a way to delete all unranked maps (Options -> Maintenance), but no way to delete maps I never played. I have 9.5 thousand maps and I would like to clear some space on my HDD by removing the ones I've never played.
Fix: I just want to delete fully unplayed mapsets, not only easy/normal diffs.
