Sounds great! I'm very glad someone has taken up this challenge.

I'm not sure I understand your intention here. This does not sound 
like a new view to me. To me this sounds like an action, say 'Arrange'
that should be added to the current UMLView.
See OGLViews.UMLView.__init__. Currently 'Toggle Attributes' and
'Toggle Methods' are such actions, just extend this list.

If you do want to add a new view to a model, the best advice (advice
I follow myself) is to copy/paste from a similar view and work from
there. To have the new view show up in the Views menu, it has to be
added to the models associated controller class. There are two view
lists attributes in the controller, DefaultViews and AdditionalViews.
Usually the new view class would be added to AdditionalViews.
