Finally! avant-window-navigator-0.1.1 is out the door, and after some teething pains, all seems well.
To help people grasp the idea a little better, I have posted some screenshots here.
Also, I have made a screencast (download awn-demo.ogg) which gives you an idea of how Awn works/looks when you are using it (it was my first ever screencast, so forgive the lack of direction :).
If you are using Awn, and hopefully enjoying it, I would love to here from you regarding what features you'd like to see, and/or any ideas regarding the visuals.
