DAW like features.
I believe the number of available tracks (24) is fine for novice, intermediate or advanced user for arranging songs using the genres BIAB represents. However, a straight forward ARM > record for audio would make it whole for many hobbyists. Is the "method" present, yes. But as it stands, it's way too convoluted for a person who is either used to DAW recording (past 25 years) or novice, who doesn't want to dig through menus to accomplish a simple task. From the actual conversations I've had with musicians who potentially would want to use BIAB to create backing tracks and record 2-5 takes of their own instrument... They don't want to learn 2 programs. They don't need 90% of bells and whistles DAW (or RB) has to offer. They just need a handful of tracks on top of backing for their instrument/vocals. I believe making process of audio recording in BIAB smooth could bring a different group of people. For someone like me, I would very much like the ability to do some sketches while in BIAB (the easy way) to see how arrangement works with vocals and make corresponding changes before exporting.

Also Per-track volume automation for all tracks would be great. Since code for string&node automation is available in BIAB already, that would qualify for workflow enhancement... And a DAW like feature.

P.S. Charlie. We (I hope) are talking about workflow enhancements. The point your were trying to convey is a workaround / alternative to a better and simpler workflow that I offered. Mine would have less steps, easier to navigate, visualize and execute. I didn't dodge it, I ignored it, because it is not what is being proposed.
