Mostly in my head, but I have deliberately emailed the list when I have
what I think are fairly solid ideas for the way ahead. But it is not a
terrific place to store it. Just ask.

I have started adding some of this, with the idea of seeding activity (I
don't myself really understand it). Look in
denemo/actions/menus/ObjectMenu/Instruments/Percussion
in the latest git (this will be installed with the program in the next
release, assuming we can work the mechanics of it out).
What you find there are commands which can be added to the menu system
(and given keyboard shortcuts). The commands themselves run scheme
scripts which do whatever is needed, without the user needing to
understand LilyPond syntax etc.
The ones I have done are from suggestions in the mailing list from
people interested in percussion - there's plenty more to be done, single
line staves, cross-head notes, Drum Clef etc. Probably all of this can
be done with very simple scripts.

What we have is the ability to write scripts in Scheme (hence the
view->Show Scheme menu item in the view menu). With a script it looks
like we can cater for almost user needs, without the program becoming
overloaded.
I am not quite sure if "plugin" is the conventional term for these -
they can end up in the menu system of the program once they have been
imported, and hence they can be accessed from the keyboard via
keypresses of the user's choice.
It would be great if we could get a fairly complete percussion support
in the next release (say in a month?) - at the moment I am just fleshing
out the scheme interface.
