After I got my 27" iMac six months ago, it came with Lion. My Unsanity WindowShades no longer worked. Now I've got Mountain Lion, which is even farther from Windowshades. After going through hours of fruitless searching and experimenting, I gave up on Unsanity's WindowShades.
However, I've discovered an app that is very much like Unsanity Windowshade. It works beautifully. It's called WindowMizer. It can be found either at RGBWorld, or the Mac App Store. It cost me $9.95.
I spoke with Chris, the inventor and programmer of this app. Though the app works great now, he told me it will be even better in two weeks when he tweaks a few little things and sends out the update.
I loved the Windowshade app because I have to have a lot of windows on my desktop when working.
It's a drag to minimize them by have them get sucked into the dock...then "unsucked" back onto the desktop when needed. I need to see the title of each window on the desktop to easily open and shut the window, without losing the title bar.
This app is certainly the answer. I'd give it 4 1/2 stars out of 5. It'll get 5 with the updates. I couldn't be happier.
