The reality is that not all suggestions will be implemented.
That's inevitable for a number of reasons.

I'm pleased to see that one of mine is amongst this year's list.
I note that OM's "user dictated arpeggios" is there, too.
I have yet to get 2023 and try them.

But it does seem a bit perverse that the "with my chords" preview is available in one program and not the others. Clearly there's history to this, but I puzzle somewhat why a function obviously common to several parts of the BiaB/RB suite wasn't built originally with multiple use in mind right from the start in any new package. To not do that is storing up work and heartache for the future. In theory object-oriented languages like Delphi are supposed to make 'things' for reuse easier easier, but my own (limited!) usage of OO languages seems to me sometimes to suggest otherwise. YMMV.

I know from my own, fortunately occasional, experience that sometimes "we should have dealt with this way back in [insert occasion] but it's too hard/late now".
