I'm on arch right now so I'm going to download and edit in a minute!

Edit: Installing it as a hassle -- sooooooooo many dependencies, and a lot of them from git so it took a while to download the big ones (and I'm on a pretty decent connection). That said, it's pretty barebones, for now. When you open it there's just a page with an address bar in the middle, and typing into there takes you where you want to go. It'll either do a search for what you type or go to the address. There's no address bar at the top of the page you're viewing, but in any page you can press TAB and get a little HUD with the aforementioned tree history view and an address bar.

Overall, it's pretty, but not that functional as of yet. Certainly not revolutionizing, but it's pretty and I'll probably check on it every once in a while.

Edit2: crashed when I tried to view a .swf file on it.

Edit3: Ok it crashes quite a lot, at least on my machine.
