I've been looking at the new features and all for 2022 (I have 2021). Haven't seen anything definitive about using BIAB for sets in live performance.

One of the things a lot of similar posts in the requests forum miss is that it's great to have the full BIAB running on stage so if you're doing a song other musicians aren't as familiar with a particular song (say they're sitting in and a song is requested they don't know but the rest of the band does) the chords can be seen and followed.

And me, of failing memory, would love to see the chords while doing a solo for songs I've more recently learned.

So that is the main reason I would love to use BIAB in a live context - but until building a set list with it is feasible, it's a no go.
