Yes, for Grammer 3, I will make sure to have a good readme (That is a good idea)

EDIT: Yeong asked about adding a menu hook in Grammer 3 and that reminded me about some of the other menu features that I think would be awesome.
Since Grammer 3 won't be using the OS menu system, I will definitely be adding a way to make a customisable MenuKey that works like my MenuKeyHook. I will also make it easy for the user to add in extra, customisable menus, too.

Also, since I plan to have custom command sets, I will probably leave the F1 to F4 keys as changing menus depending on what command sets you have loaded. F5 will probably be the custom menu.
