Do I hear open source?
Prehaps after the season you should put this up on sourceforge. After all, why not?
One feature I'd hope to see in the local app would be the capability to access remote databases. I'd want one computer to act as a server and others to access it. Even if that computer is a webserver, it'd be good enough :O Of course, I can dream of more features
If there's anyway I can help add any features, please leave me a pm.
