I guess I am a minority, but I would like BIAB to adopt a few of very particular DAW features. Specifically simple multi track recorder.
All the functions are already in place in BIAB. Also a new Track View is there. It's just the way this (record vocals or instrument) can be achieved now... to put it gently is awkward at best.
A simple: "select input" "arm" / "record" on the actual track header will solve this.
This will be especially beneficial to a singer/song writer who doesn't need, or doesn't want to learn another piece of software and just needs a few tracks to lay out their input. For someone like me, it could be used as a scratch pad. To record some ideas / snippets / reference, while still be able to change arrangement without constant import/export and jumping from software to software.

MIDI.
Besides content, I would like MIDI to have proper routing. For example from one track to another, or one instrument to another. Simple example: A midi plugin Scaler, Re-midi, or even EZ line of plugins and whole lot of others that can output midi > routed to a sound producing VST synth. DAW feature? Maybe. It's missing. I want it!

I know these are wishlist things, but since it's an active conversation, these are my 2 cents.

P.S. Kindly don't mention RB. I am glad that somebody finds it useful, but those who don't, likely know the reasons why I am asking not to mention it here.
