Unless I'm missing something, would it be possible to have a way to show and edit attributes of elements. It's nice to be able to navigate the elements, but Not being able to edit edit the attributes along with the elements in both the graph and the outline is kinda incomplete. Not global Atrributes, but Elements Scoped attributes.

Make sure you have the "Properties" view open while you are navigating the elements in the tree, that is where all the information is shown and can be edited.

That helps, but isn't quite enough. I'd really like to display/(delete add) said attributes in the graph view. At least display them. When you have a very very complicated schema that you are developing, it's nice to have someplace you can go to see a picture of the whole thing. The drag and drop that is there is nice, but would be even cooler if you could move a copy an element arround, as well.
