This would still be a very useful feature.
I’m working on a piece now without time signatures, but with different number of beats in the bars, and lots of repeat signs. I cannot use “add bar” because it doesn’t work without a time signature (this makes sense), but when I use the insert mode it shifts all notes forward but NOT my barlines or repeats, and so all my notes end up in different bars that I intended.
I think Dorico should assume that you placed your handmade barlines in the right place relative to the notes that come before and after them, and move them when you insert notes (or at least give you the option).
Thanks –
