It's kind of a keyboard driven application window multi-tool..
It lets you move, resize & tile groups of windows from the keyboard. It also works as an alternative window switcher.
There's a screencast on the site giving a demo. I'd really appreciate any feedback on if it: does it make sense to you and what new features would be most useful?
The tiling is great, but I would also like to be able to instantly move a single window to a desired position instead of only being able to tile... I'm sure this could be done with a similar interface that tiling has, only available with one selection though. I also really like the dual monitor support.
One thing I think would help would be able to show the keyboard shortcut panel when WindowFlow is activated but hide it when it's gone. Right now it seems that you can either have it showing all the time or not at all, so you have to manually toggle it on and off when WindowFlow is active to see your options.
Also, I believe that "option" should be used instead of "alt" on Macs. I know the key says alt as well, but option is more prominent and it's the standard in the Apple world.

Hope this helps, I'll use it for a while and see if I can get used to it. The selection interface does seem a bit awkward at first for me.
I was thinking you could do something with selection of the first 9 applications with number keys, similar to how TextMate does it, but that conflicts with the shortcuts for tiling. It's an idea anyway, I don't know if you could figure out a way to make that kind of thing work...
Yes being able to get one window to jump to a particular position would be really handy. There's a shortcut to center a window on screen, I'll add ones for the edges.
