two questions: one, if menu is purchased as a single user, can it be upgraded to another level in the future for the price difference?

also, is there a way to a) popup up a menu item (e.g. one containing a div) programmatically/from within code? & b) make it sticky (i.e., it doesn't go away when the mouse moves out, but closure is controlled through code)...if not, any ideas on if/when these features would be implemented?

thanks....
