If not so already, please let keys be assigned to user-defined zoom states.
For example, I define a zoom that puts the midi window nearly full-screen and assign the A key to it. etc.
Would love to be able to tap a single key to bring up pre-defined zooms.
Regarding audition - please have a process that runs on user request to render all libarary clips to a wav, allowing all clip previews to be pulled from the pre-rendered cache. Perhaps this is what the scrubbable auditions is doing.
Also, when arrowing through library clips, have threads that are preloading the next 2 or 3 clips so that previews (from the above mentioned clip preview pre-render cache) are near instant. Having to wait for a clip preview to load takes a lot of the usefulness away.
