a better osu!mania in regards with rate mod, custom timing setting (like wife in etterna but isnt a pain to set up here) compativility with .osz and .sm files and a neat option to activate the note accuracy bar that tells you wheter the last note is hit late or soon (osu also has this, but its bar isnt dynamic and its harder to tell in a split second wheter it was late or soon) the ui and search function works well, but i do hope in the future skinning can let you edit all parts of the ui. 4k and 7k ranks are differentiated and thats great. a multiplayer system where you can play with different rates is also great allowing you to play with your friends that are way above (or below) in terms of your skill level. but, the difficulty calculator while still a bit better then osu it still got some flaws, ranked charts are a letdown but i see things getting better now.
