Loop Screen / Cycle Region
Unless I'm missing something - If you're editing a long pattern and want to work on the final bar there seems to be no way of doing this without listening to the entire sequence over and over. This gets pretty tedious, if not unworkable, when working on 8 bar patterns and over.
The Tempest has a toggle function 'loop screen' which just loops the currently visible area. I I think something like this is really needed on the Deluge - particularly as it can deal with such long track lengths.
Maybe this could be set in 'track' or 'song' mode?
