Essentially just like edit mode but whit training where you can start playing a map from any point in the song, with all the mods, save replays, overlay your replay on one that's made by AUTO so you can see where you shou8ld have done something differently, our better yet have an AUTOGUIDE mode where the cursor of an AUTO replay is faintly overplayed so the player can follow the cursor and learn the map better and faster. Also be able to skip around in replays, slow them down to even 0.001x of its original speed etc etc. This would help players to improve better and faster then ever before raising the skill ceiling, adds a wait to improve fast for new players. etc etc, im sure people have other ideas they would like in a training mode.
