I would like if it was posible to mark blocks in the songeditor and then move them freely. An option to mark ALL (like ctrl-a) would also be very usefull.
when arangeing a piece sometimes the piece needs a new intro.. something completely new like an effect or a new instrument leading in to the piece. In that case it is very difficult to manually move say 50 blocks over say 19 tracks, and a bulk move would make that operation very simple.
To sum up
*multimove several specific marked block on several tracks
* mark a track (or several) and only move blocks on those marked tracks
*move ALL blocks on ALL tracks simultanous.
