Very nice. Looking foward to fullscreen and undo. I've really been in love with the whole desktop wiki thing. I've been using vim, but this looks like it could be a replacement... there's really no other way to easily organize a large number of files, and to talk about files and their relationship to each other. I hope they come up with an operating system, someday, where it's possible to draw or write on the file explorer window, because it's really ridiculous having to describe a files with a name, an extension, and the position. Forget the syupid physical metaphors (microsoft surface, 3d desktops, piles, etc), give me an editable surface any day.
