Charlie,
Thank you for your time!

Most of these have to to with audio, not specifically working with PGmusic content....
There are a couple of interesting items.
Specifically these two:

* can record Mixer automation in real time. - Assuming automation of nodes with external controller (for audio AND RTs?).

* makes it easy to create a UserTrack. - I guess that is not very practical in BIAB because of 255 bar limit? I will read on this. I wish there would be a better way to create UserTracks in BIAB. A wizard with various templates, punch in recording, note correction and that kind of stuff. So it guides not only with recording process, but "save" process too. My take, current process confusing people, that's why not too many people creating them. I don't consider myself complete noob, but even I asked pipeline to help assembling couple of User Tracks (that we made public)

This is a good one too:
"has 3 ways to display time: either bars/beats, time or frames passage."

This I don't get: "has scraps feature (ability to select, load and save regions of audio)"
Well I kind of do... I assume this is mainly for audio, not RTs.
