Good job!

I recently downloaded source for Umbrello Beta 2, compiled and installed 
without a hitch.
I truly appeciate the improvements. Find attached a screenshot.
Now a question.
I would like to use the umbrello infrastructure to develop the 
application. Instead of working with
the UML objects I would be working the the instances of the classes; 
would edit the attributes and call the methods.
The listview pannel would hold my objects.
Persistency of the application would use an xmi file. Could use 
read/write/edit functionality of umbrello to
add objects / edit attributes / call methods. Attribute nodes / menubar 
/ toolbars would be populated  directly from the umbrello xmi file.
Any examples of this kind of work?
Would appreciate comments / suggestions

Thanks
