Hi Fredrik,
Thanks for the feedback. That's indeed a long-term goal of mine. I decided to release this version because I just wanted to start shipping and getting feedback. The project has been half-done on my desk for more than a year now, so I decided to just ship something that works, even if I know there are rough edges to it.
I have an idea of selecting a design element, and then having a diagram showing of all elements depending on the previously selected design element.
It'll mean a change in the way I parse the database design, though. But a nice challenge!
