Reality is, 95% of ideas offered specifically concerning "DAW like features" are related to enhancing existing features/functions in BIAB.

"define what user workflow we're aiming at."

My take:

Reducing obscure complexity both in number and wording of menus - better sorting. Consolidate related menu items.

Easy access to common functions and tools, completing under-developed features > getting rid of obsolete ideas. Example: modal/non modal Partial Regeneration

Moving tools to Panels

Navigation, zoom and consistency of project views which includes minor adjustment to transport.

Customization of UI - detachable tools, custom colors & buttons, second/third screens compatibility, etc.

Completing Track View. Proper start marker, tracks on demand (not displaying all), proper ARM, zooming / expanding individual tracks, bringing editing tools from AE. A cherry topper would be per-track volume automation. If done right, AE can be removed as there would not be need in it. Less (unneeded) complexity - better workflow.

And yes, I would like a toggle between RT and MIDI notation on demand, since feature is present, but masked for unknown reason.
