Those convenience wrappers are good to use (I didn't write them, so I
tend to forget their existence, my memory is really only good for the
basics)

Well, I'm hoping that if I provide you with enough material you will be
able to assemble a useful Gregorian Chant Palette before release 2.10
- one with the most used commands early in the palette and the clearest
sort of indications in the display. I would leave re-ordering the
buttons to the last, when you have decided on the set of useful
commands.
Also, did I mention this? - I think a Quit button on the palette would
be good, as it could revert to the normal key-bindings (I'm thinking it
will be good to make the New button set up keybindings for things like
the space bar, which are useless in Gregorian chant).

Is it the case that the Augmentum bug has no workaround yet? I could
work on creating a Denemo version using markup. If so, which are the
groups that need it? (I know about the \pes one, which was the one I
reported to lilypond-user without success, but I guess there are
others...)
