Since I first learned objc and cocoa, many of things have happened. first Tiger, then Leopard and Snow Leopard, each time cocoa have been improved and in some cases been significantly changed in ways that makes it easier to make programs. Lately I have been reading up on some of these things (ibplugin and nsviewcontroller), which I plan to use at some point in the future for GDT.

I'm very interested in getting an iPad, since it could be fun to port GDT to it.
