I would like to control the right click context menu, and i think the easiest way to do this would be allowing multiple instances of classic shell to run, and adding an option to the controls tab, that allows you to set "Right Click opens:" (the right click context isnt really necessary, as anything on it you could add to your start menu already, and you could exit with task manager if you need to..)
I don't think actually adding a second set of options specifically for a secondary menu is a good idea however, because i doubt most users would need it, and it would be rather confusing.. (unless you can think of a better way to do it
)
Also I previously requested an option to add the options you receive with win+x (on windows 8) with the right click context menu. but this request would be greatly preferable to that
(and that option would be pretty useless with the power this one gives)
EDIT/UPDATE: actually, there might be a better easier way than running multiple instances.. and thats to load an alternate Menu Settings.xml on left click (or whatever options are set to open alternate start menu)
