I have no hope for Unsanity. In the past, they often took several months to get updates out for new systems; but they should have had something for Lion by this time. Instead, they're busy soliciting donations so that maybe, just possibly, they'll consider upgrading. (But only if everyone re-buys all of their software first!)
So, if you want to windowshade, Deskovery is your only option. But it's not an option if you want to windowshade the way all of us have always understood that to work. As best as I can tell, Deskovery attempts to pull it all off by moving windows to their own little Deskovery world, and the magic takes place there. The problem, as many have noted, is that windowshaded windows are no longer readily accessible unless you click directly on the window.
This approach is pointless, particularly if you're using a keyboard. For instance, if I have two windows open, and I windowshade one and then switch to the other, I cannot use a keyboard shortcut to switch back to the shaded window and unshade it. The shaded window is no longer part of the program I'm working in; it's now a part of the Deskovery world.
I think the developers are trying this approach in order to avoid injecting some kind of system-wide program, in order to avoid accusations of having something like APE (for which Unsanity is always taking a beating). I applaud the logic but not the result. Frankly, APE never gave me any problems over the years.
At any rate, the best alternatives I've found to windowshading are either SizeUp (because it allows a nice bounce-back feature) or simply to minimize windows to the dock and then use various programs such as Hyperdock to relocate them.
Alas, everyone's presumably repeated pleas to Apple to reinstate windowshading have gone unheaded. They want to get pi$$y because people use APE; but they don't want to provide their own windowshading solution. Even Microsoft has windowshading programs available. Sigh.
