wxSmith change control sizer order / hierarchy

[bugmenot]

After much frustration and searching I found you can change the control order / nesting of wxSmith by using drag and drop. Now this is only possible if you give your sizers some border so there is some thing to drop on.

This should really be in docs or faq somewhere!!   :x  :x It would be nice to be able to drag and drop in the resources pane tree also, like wxformbuilder.
