I don't see any way to view/select among the open diagrams, other than the tabs along the top of the window. I always have a boatload of open diagrams, and the one I want is never in the visible portion. So I go over to the gallery and find what I want. But I have a boatload of diagrams there too, and I sometimes grab the wrong one.

It would be wonderful a) if the gallery somehow flagged all open diagrams visually, b) if the list of tabs could (optionally) be expanded to multiple lines, and c) if the inspector had a view that listed all open diagrams (e.g. if I have no object selected).

Perhaps there's already a way to see this info, but I'm not finding it.
