"What will get more users back ?"
Here is my recipe:

1) Known bugs fixed
2) VST3 with full mixer channel routing before the end of the year.
3) Workflow enhancements / fix broken workflow items - the core of these issues was presented in great detail in several videos by Jeff P.
4) Throw out redundant features and menus /Clean up UI., not giving in to a vocal "few"... only few (!) that are stalling the progress for most users because they are too comfy using certain menus.
5) Graphical enhancements. More vector, more modular, modern buttons. No eyesore "Radio Bar" by default. Less of 90's vibe in design.
6) Plugin stability + same regeneration multicore speed as BIAB. No render to disc.
