Wondering if such a thing exists?
I know I can color-code voices (e.g., /voiceOne, etc.) but I'm thinking about annotated output for all contexts, staves, voices (something like the Annotate Spacing option).
Because LP is written to create implicit contexts it is sometimes difficult to see what's being done by LP when it parses code if things go awry. Having contexts, named or otherwise, shown in the output would be helpful. I recently tried to move lyric output above a staff in a temporary polyphonic context and could not get it to work on my own. I eventually found a snippet that the job. Having LP show which contexts are which might have revealed why my \lyricsto "name" was not working.
