midbrowser seems kinda crappy to me.
I've been intrigued by Prism, it has a very very tiny UI; it is basically XULrunner in a window. I would love to see a browser that is just a tiny bit more robust than Prism, basically just add an address bar and some back/forward/stop buttons. Then, if I can install Grab and Drag, it would be very, very sweet indeed.
