I'd like to see a new Mod Choice in osu! that allows you to "stop" a song at a certain point and then "stop" it again at another. So you can play that part over and over to perfect it. Sort of like a Point A - Point B quality. My friends and I are trying to beat a song together but we all get up to one point and fail. But if we have No Fail on we feel like we're not doing it correctly because we miss a lot. We can call this function "Stop Watch" or something of the like!
