Just an aside or an addition. I have been using Deskovery for a while now. Works OK even in yosemite. I do like WindowMizer better though for a couple of reasons.
Window Shade For Mac
WindowMizer is a Mac application that will roll-up your windows like a windowshade.
Window Shade Mac Os
First it renders better on the Retina display and Second it brings back sound to the interaction. Apple has been dropping the ball for a while now on the user interface and I think it may have all started when WindowShade was abandoned. Too many bad things in 10.10 to list here but Windomizer seems to be a major step in the right direction. Since there are too many annoying features in ML I am sticking to OS10.6 for the foreseeable future.
Even so, and despite my love of Windowshade, I have stopped using the unsanity haxie. If you forget to turn off the APE module before a system upgrade it screws you up, and you'll be in so many endless loops that your battery consumption will go way down due to all the hard work the processor is doing. My computer has run so much more reliably since I got rid of it.
Looking forward to trying windowmizer.
WindowMizer is an application that will 'roll-up' your windows like a windowshade. It quickly collapses a window leaving only the title bar visible. This allows you to see what's behind the front window without losing your place or focus. Simply double-click on the title bar of a window and it will roll-up like a window-shade. The window is now out of the way yet easily accessible.
Double-click again and the window restores to its original size and position. Window-shaded windows provide quick, intuative access to all of your windows because windows stay where you put them and you can see all your windows at What's New in WindowMizer.

Stop digging through your windows trying to find the one your looking for. Reduce screen clutter and maintain an organized desktop when working with a multitude of windows and limited screen space.
