Yes, that's exactly what I'm working on. I have chord grids fully implemented and working, I've added support for ABC sections and files, lowercase chords are now accepted (with a setting to control that behavior), and I'm working on the prefined page sizes and chord diagrams. Adding settings specifically for comments wasn't on my list of things to do though. Was that something you previously asked for? I know you talked about reworking some of the settings, but I don't have a concrete design in mind for that at the moment. I'm just going through one thing at a time right now.
