After the horror of file conversion in UMENU v1, and especially after
what people on DNG have said about dir/file tree being a good idea,
more than ever I'm thinking a native format of dir/file trees,
supported by text editors, and/or file managers, and/or specialized
submenu config helpers, might be the way to go.

Given that my current design reloads the config file for each submenu,
"less than a second" is no good: It needs to be "less than .4 seconds"
at a minimum, and "less than 100ms" would be much better. Menus start
losing their competitive edge when you can type faster than they can
process your keystrokes.
