I’d ALSO love to see WindowShading! I am not a computer-trained person, but I have been using Macs since 1990 and I have certain approaches to efficiency that I have accumulated over the years, particularly using keyboard shortcuts (from the OS and third-party, like QuicKeys and Keyboard Maestro). I also used Unsanity's WindowShade X until they just couldn't keep up with the annual Apple OS upgrades 2 or 3 years back. But windowshading was so convenient in OS 9: If you wanted to see directly underneath a window only momentarily, all you had to do was double-click the title bar of the window and it would “windowshade up;” then, leave your cursor in place as you looked briefly at whatever contents that were directly underneath the top window; and then double-click the same title bar again to resume your work. The cursor never had to move! Since OS X, you have to grab the title bar and move it out of the way to see the contents below your top file/folder. It’s NOT the same as “four-finger” swipe up on the trackpad (Mission Control) to see all of your windows and then select a file or folder, because everything is too small and you can’t read anything at that point! And I know I could use MC and click on the 2nd window, read it, go back to MC, select initial window, but that's four gestures as opposed to the steps I listed above for windowshading. To clarify to those who are post-OS 9 users and who never used WindowShade X from Unsanity, you would windowshade several files/folders and leave them in that windowshaded position on screen until you were ready to open them up. I know MC can do something equivalent to this, but it certainly can't do what I initially described above. Meanwhile, I will check into TotalFinder that someone mentioned above.
