I would like almost everything on page 1 of top voted at Centercode:
Grouping within a group
Edit Multiple Midi-Clips
In-clip audio editing
Freeze and Flatten side-chained tracks
Bounce in Place
Tagging plug-ins by category
Comping tool
MP3 export
Automation snap to Grid
More than 8 macros
Graphics Elements compensation
EQ8 Linear mode / dynamic eq + More Filter Slope options for EQ8.
chord Identification in piano roll
custom keyboard shortcuts
Undo after save!
Add more curves for automations
Not from top voted page 1:
Chase MIDI notes (being able to play from middle of MIDI note)
Native modulation (LFO, envelope generator, etc.)
Being able to adjust knobs of automated parameters
Type automation values with keyboard
Clip background colour in arrangement view
More MIDI editing tools (split, click+drag draw, strum, etc)
Double-click to create MIDI clips in arrangement view
Plugin sandbox (crash protection)
Show/hide tracks
Inline piano roll in arrangement view
And have pitch bend reset to 0! Shit's driving me mad:
SUG-0986: make it so Pitch Bend in MIDI clip modulation does not get stuck on old values
