Hello all, I just drafted a new release (1.0) of Spontini-Editor, which is now compatible with LilyPond 2.23.0 to 4
https://github.com/paopre/Spontini Furthermore, it offers a tool that allows you to include or exclude blocks from the building process of the score. I encourage the use of the editor, which I could test intensively, because it is essentially bug-free, it works perfectly on a Raspberry PI (or any similar cheap hw) and it allows you to create *very complex* piano scores. Any feedback is greatly appreciated! HTH P.
