New song section mode - more than one pattern per song using the same tracks
The problem with song section mode as it is now, is that you have to duplicate tracks to make new sections. This means that if you do a complex arrangement with many tracks and sections, the number of tracks easily grow astronomical.
What would have been really nice was if you could make more than one pattern per song, and re-use the existing tracks for all patterns. This calls for another "new" song section mode. I believe the colour codes of the song sections could still be used for this, if there was a third "arrangement" view where patterns could be arranged. This would allow for a much better workflow with big arrangements with many tracks or sections, and I believe it would improve the sequencer part quite a lot making the Deluge more usable to more people, especially those who uses it to sequence other equipment!
