When you have a very complex song, it's very cumbersome to have to shift+click+drag each individual pattern/beat/bassline and piano roll in order to extend the song and repeat certain sections. It would be very nice if a feature were added that would allow me to shift-drag all patterns that are selected with the selection tool on the song screen (Which is pretty useless to me, as all it does currently is make deleting large sections easier?), or allow me to Copy+Paste a selection. It really messes up my work-flow having to shift-drag each individual section of each individual track.
