#1
(cuz it will help achieve #2 and #4. #4 due to how it reduces cpu utilization for plugins not processing audio at a particular point in time.)
- nested track folders, please!
- bus folders! (n-deep, nest-able, of course)
- full color customization of absolutely everything. if certain UI elements must be image-based, perhaps an xml file to make them editable with a user-generated image replacement folder. not even full theme-ing, just the ability to tweak the existing artwork for getting our darker themes happening, would be huge. :-) if you do this, i'll make a dark colorized theme for us.
- an alternate mode / setting for the audio engine to force it to favor pre-buffering over low-latency (for those times when it comes in handy)
- a larger, more customizable area uptop, above the time rulers, for visually defining the song parts (intro, verse, chorus, etc.)
- more logic-like bezier curve tools for the automation lanes
- ability to have several instances of the console window open, with per-track settings, or smart rules for showing / hiding different types of channels (for those of us with several monitors) :-)
- allow VST windows to remember their width when they are narrower than the VST toolbar
