I'm not convinced by this.  The very tight coupleing of these classes
just means there is extra work to get at variables etc, but does not
simplify much when changes are made to the structure.

Parse error on sentence.  

The WidgetData classes are base classes but there would not exist any
WidgetData classes

Do you mean it's a two step move where WidgetData classes are base
classes then are got rid of altogether?

You'd need to be careful to keep the file loading and saveing working,
probably similarly with the clipboard.

But I think it would be a simplification if done (maybe Jens can argue
otherwise though).
