It would indeed.  Anybody volunteer to implement it?

I'm not going to implement this, as there are much more basic things I need
to look at (text input, text rendering speed).  If anybody does want to
implement it, I would suggest starting by making something that can 'fix'
the current defaults under a name, and apply them to the selected objects.
That'll give a lot of functionality with a simple interface, and I believe
dealing with the properties system enough to do thing would take some
work:)

Yes, in the long run it'd be great to have CSS-like styles that can be
saved with the diagram, applied logically to elements etc.  But unless
somebody hands me down a complete implementation, that's going to be
post-1.0.

Why don't y'all start an area on the Wiki fleshing out these ideas?
