more of a window resizing plugin, not a "window manager" at all. i guess that's what the mac users have gotten to calling these things though. how is it different than BetterSnap and the army of similar tools? and more important, how is it better. is the differentiator that it is the only open source such plugin? these advantages should be highlighted in the README, and the screen movie thing should show them. i only see half screen tiling demoed, this has existed for a long time with any number of tools. also how will it differ from sequoia. AFAICT the unique thing here is the radial menu. i do like that a lot.
