Palette magic

[mzieg]

The Control Palette (scrolling area at right) is a bit unmanageable, especially in Expert mode. Recommended redesign:

• Give each widget a little 2-button bar to the right of the title, which is only visible if you point the mouse at it.
• One button should minimize / expand the widget (reduce to just the title row), similar to what we have in ThumbnailWidgets.
• Another button should detach the widget and make it a floating dialog. I don't know how hard this would be, but in my mind, we could just instantiate a new QDialog, and then change the QWidget.parent to that. We'd want to retain a handle to the original parent (and perhaps item index) so if the dialog was closed, the widget could be re-parented back to the original owner and position. Could be easy?
• Would also be nice if you could click and drag widgets by their headline to reposition them in the list
