At the moment the GUI will organize the items from top left to bottom right according to the space that the screen has available. Because the authorization will be different for users the tile menu will be changed based on the tiles the user have rights to approach.
It would be nice if users can design their own tile menu with a similar functionality (Drag and drop, Resize) as in the SF menu designer.
It would definitely boost user-friendliness 
I like this idea, not only for the Windows and Web GUI, but also for the Universal GUI
