Was about to buy Divvy but kept looking because it doesn't seem Divvy receives updates anymore, then I found WinDock. It's amazing! Simple setup and works like a charm! I really hope WinDock will work the way it does now for as long as I am on Windows.

I've set DPI-Sacling in Windows 7 to 125%, now the windows take not half ow width heigt, but 125% of half width / height when docked.

Also thr right edge of screen, and the top and bottem right corner are not recognized anymore.

Besides this, I like the simple but powerful configuration.
