I would very much like the option to place the panel showing track name, volume, pan, sends, etc. on the left-hand side of the clips in Arrangement view.
I think Live is pretty unique in having the information on the right-hand side of the screen. It may be just me, but it feels more natural to have the information on the left.
Also, a little UI work on the track lane information would be useful - we have pan and sends as numbers and I think a graphic element (a dial or slider) would convey more information more quickly.
