Simpleshade - 1.2

Keep Simpleshade in your Dock to immediately collapse or uncollapse all Finder windows by clicking its Dock icon. To put it into your Dock, just double-click its icon. To keep it in the Dock, drag it there while it's not running, control-click the Dock icon while it is running and select Keep In Dock, or use the login system preference to make it launch on startup. Note: Whenever Simpleshade is launched or clicked in the Dock, it will make the Finder the frontmost application. To quit, control-click Simpleshade's Dock icon and choose quit.
Now included is Smartshade. Smartshade works just like Simpleshade except that it restores window sizes more precisely when unshading. Smartshade is necessarily slower than Simpleshade, because it preserves original window dimensions before shading the windows. If you repeatedly click Smartshade without giving it time to finish shading or unshading all the windows, it will quit without warning. You may start it again immediately, and it should continue to work.
