Hi, yes that would be great!
I think it would be nice if there would be a 'Menubar Area' in the "widgets" menu. So you can move the widgets in&out. For example than you can add 'social network' widgets move in the menu header, and change the positions.
There is a plugin i tried to use, called: MENUBAR WIDGETS, but this only works half in Jupiter 4..
And plugins that work only half are more like: "Useless".
So bring it on!! Number Five!
