Yes. I think GuiEditor itself should just be a frontend tool class, just like 
QPainter.

As 'backend' I would like not to use anything dedicated though, but instead 
try to map everything to the existing API. So for example a action group 
placeholder would just be an invisible separator QAction. And in order to 
determine to which component an action belongs to we could just look at the 
parent(), and by that require actions to have proper parents. That also makes 
all actions automatically disappear from the GUI if the plugin is deleted.

Either that or we add support for reading xml/writing xml files. Perhaps it 
would make sense to use the same format as Qt designer/uic...
