That 3rd party software where you can change beatmap bpm, AR, CS and so on. I would like to see simmilar options in original osu! where you could pick beatmap AR, CS, HP and so on. It would make map unranked (like some mods does). I want to practice AR10, but there are not that many low star beatmaps with AR10 or I have to play DT. I think this would make osu! more enjoyable for those who can't play maps with specific settings, they could chose all maps to be in specific settings to play with settings they already know how to play or with settings where they could practice and learn. (at this point my goal with this would be to set every map to AR10 so I could learn to read it).
