Cinch: Better window management for your Mac

Cinch gives you simple, mouse-driven window management by defining the left, right, and top edges of your screen as 'hot zones'. Drag a window until the mouse cursor enters one of these zones then drop the window to have it cinch into place. Cinching to the left or right edges of the screen will resize the window to fill exactly half the screen, allowing you to easily compare two windows side-by-side (splitscreen). Cinching to the top edge of the screen will resize the window to fill the entire screen (fullscreen). Dragging a window away from its cinched position will restore the window to its original size.

I'm diggin that desktop/laptop background for some reason. Simple and clean lines. Kind of retro looking to me. Thx for the posting.

But btw. when I click on download, its starts to download the app, without me having to pay... and I even can install it...
Is there a reason for that?
