Howdy,
I'm not sure if you still need something to help, but just in case someone else comes looking I've written up some rough notes that's helped a few people. (Although I do need to update it for the latest version when I get some spare time).
Info on adding custom columns can be found here:

I've also recently done a mod for someone who's just after the Due date column (rather easy mod), that info can be foun here:

Hopefully one of these resources helps someone.
Andrew
