I rarely opay a C#D box, never played a BC before, and I will use this one for irish music.
You may be right that I have enough notes on this box
I agree it may be a limitation that some notes are only available on push and some only on pull. What I like on this box is that the left hand chords have no sharps or flats, so you can play major or minor scales with them.
Your suggestion helps as for Now I only have the F# in one direction, same for the F. So when I just turn some plates on the accidentals row, I will have them on push and pull. I think the one I got it from used it for the fast repeated note effect (using two fingers on two buttons for that), but I think I prefer to have the F/F# and A-G buttons (and others) in different bellows directions (compared to row 1 and 2).
As this is a conversion of a CG box, some of the accidentals are on the lower part of the right hand keyboard, some of them I may change to thr `normal` diatonic scales when I put the same notes somewhere on the 3d row.
