You can have the same control or set of controls appear in more than 1 panel. The easiest way (IMO) is to use explicit V links from the panel with the controls to the differnt modules in which you want them to appear.
Interesting that you ask about resizing. I was going to try this very thing last night and couldn't think how... there's a resize primitive for bitmaps but not for vector objects. AFAIK this part is not feasible right now.
