Idk what other may wish to use this for but I find it cool.
So, i have launcher pro+. And when i create a short-cut, erase the display name and using the pic below, I get an "invisible icon"....
I use app lock to prevent access to my setting>app on my phone, and hide certain apps from the app tray. (via LP+)
(I'm sure there's some tech. reason for this, "bug")- But i love it
