I allways thought this was the way to go so I never mentioned it ;-)

I see no problem here. We also have layers and so on which are not be able to 
scale and skew. 

I think you want to make it possible to select a connector. Why should this be 
handled completely different than for shapes. The only difference is that it 
can not be modified by the default tool.

So you want to implement all that you have for shapes again for connectors? 
Like commands for delete, adding to the doc. Also when it is done differently 
we need special code to do saving and loading. 

How do you want to the printing as you need a z-Index also for the connectors 
to know when they should be painted. The way as you do it now to print the 
connectors over all other shapes is not really a solution or? It should be 
possible to have shapes that lay over to a connector. 

Also all the special code for connectors can be removed when the connectors 
are normal shapes.
