Looks really good so far
 

I've only just installed it 15 minutes ago, but so far I like what I see. I'm hoping this will be the missing piece in the puzzle of getting GTD to work for me as a comprehensive system for organizing *everything* I need or want to do. So far, I've at least managed to make it work as a smarter to-do list, but I've read the GTD book a couple times, and I know I'm still not really getting the benefits of having it all in one place.

Anyway, I'm going to give this a whirl, will probably be back with more comments.
