besides the most obviously (automation,proper eq…) mentioned before i would like to add:
1.better visibility of different regions.Its impossible to see where a region ends and a new one begins until you click on it.And it would be nice if they would a little more"plastically"looking if you know what i mean.They look like ghost copies.
2.Muting selected region(s)
3.easier/faster way to duplicate/copy regions in the edit screen (and/or a loop function for certain regions)
4.zoom out at song pointer position.Zooming is a pita,it never zooms where i currently need it and scrolling is slow.
5.improved interface when you zoom in for a closer look.Interfaces becomes sluggish then.It also freezes sometimes for a couple of seconds when i hide/show the inspector.
6.if you solo a track and “unsolo’” it again all tracks are unmuted then.The prior muted tracks should stay muted!
7.Multitouch for mute buttons.Currently not possible to press more then one mute button at once.
8.(saving own)presets for effects and chords.
9.Pad Banks,so we have more than 16 drumpads accessble (like ABCD=64 pads)
10:Mediabay:swipe to the left=delete
11.Pressing a mute button (or anything else)in the mixer channel always selects the channel immediately.I have to say that the white"blinking"mixerchannel is annoying to me.Would be nice if it behaves like in the edit screen (selects the channel only if you touch on the name or so).alternatively you could make the selected channel a little darker.Best case:do both 
12.i would like to have something like a brightness fader for the edit screen background (in the settings menu).I don’t like it THAT much to stare on a white screen.But maybe it’s just me…
13.CPU meter (or did i just overlooked it?)
14.ability to use own samples at least for the drumpads
15.Make this thread sticky
