Add left and right buttons to settings such as speed mods
One of the more tedious things in the app is having to mash so many options, such as the difficulty in speed mod. For example,maybe you want to set a song to 1.5 and accidentally tap it one more time and set it to 1.75, then you have to tap it over and over again still you get to 1.5 again since there's no back button. Same with the difficulty select. Left and Right selection buttons on settings like these would be very helpful!
