What can PySTDF do for you?

There are lots of features I could add to PySTDF, and applications I could build with it. I am primarily focused right now on developing a GUI browser to explore STDF data, because its something I've always wanted to do and never had the chance.

But I'd also like to keep a user perspective on the direction of development. What are you trying to do with STDF? What kind of tools would help you out?
