Thanks, glad to hear it. And would it be necessary to reimplement the
menu system in Lua, or would it be possible to hand over the generated
config to menu.c32 somehow? If not, then maybe extending menu.c32 with
some "dynamic" directives would be a lot easier. Unfortunately that
would restrict the functionality to the simple menu system and also make
it more rigid, but that's probably the bulk of the use cases anyway...
