I've not try it already (probably won't) because I'm not into tiling. But the author managed to write a new WM that is worth existing. It's not a copy of something else, with different defaults, so congratz for that.

Also, he told me the floating windows CAN be moved using the keyboard, which is something you don't see enough in tilling WMs.

Looks like a good WM so far, but I'm not convinced the modal approach is a good approach for window managing. See ratpoison: it's an awesome manual tiling WM. But the EMACS-like keybinds make it really painfull to use in it's default state. You can hopefully make "direct" keybinds using "definekey top", and that's why ratpoison is still the BEST TILING WM out there for me :)
