I run multiple "desktops" on Mountain Lion. However, I like to keep similar programs on the same desktop. When I do the 4-finger-upsweep on my trackpad and the current desktop minimizes and shows all of the other desktops along the top border...it's sort of hard to see what's what in the other desktops. So, my question is...is there a way to superimpose an avatar/icon on the desktop snapshots (like the "X" logo in the Dock for Microsoft's Excel, or the "W" in the Dock for Word, etc?).....so if you wanted to keep all of your Excel windows on one desktop and your Word docs on another desktop, Photoshop on a third desktop, Illustrator on a 4th desktop, etc., etc. you could put an avatar/icon on that desktop snapshot on the top border to give you a quick reference for what is on that desktop. Any thoughts on how I might accomplish this? J. P.S. Obviously when you clicked on the Desktop you wanted to switch to, the avatar/icon in the snapshot would disappear so as not to be visible when the newly-chosen desktop is full-size.
