My Mixcraft suggestions. Let me know, if any of them is somehow already possible.
1. If Selection is made, make the 'use selection' box ticked as default, or make it possible to set it that way
2. 'Don't show this message again' box, at 'You have unsaved changes' reminder (when exporting rather than closing)
3. Possibility of making longer track with selection, same way as you export it shorter
4. Saving one track as some MC file with all midi data, effects, settings etc. and then 'open saved track' or +Track -> Saved track
5. 'Mix down to new audio track' for the whole Sub-mix track
6. Loop on/off not triggering the star-reminder next to the project's name
