Gmail widget

I've been using gmail exclusively for a couple years ago, and like many of you I love it. I do miss a few features from plain ol' pine, however - mostly the ability to use the keyboard for every function. It appears that the tools to do that with gmail already exist though, and now someone has compiled them into a nice firefox extension. It also does a few other things I'm going to try out over the next couple days, but for the extended keyboard shortcuts alone it's worth it for me. Who wants to deal with a pulldown menu to add a label, anyway?
