Plugins menu too full

If you'd place them in 2 or 3 subcategories, it wouldn't clutter up the main plugin menu as much.
Example :

var mscorePlugin = {
menu: 'Plugins.ShakuhachiKinko14 Notes',
init: init,
run: run
};

Changing this to
var mscorePlugin = {
menu: 'Plugins.Shakuhachi.Kinko14 Notes',
init: init,
run: run
};

and doing this for all, would make them appear under a submenu.

I'd suggest 3 subcategories, Shakuhachi, ShakuhachiKinko and Shinobue. Maybe
