Seems that the forum won't display the apple sign ( it was supposed to be where the "?" is )
I ment the command + tab feature that lets you switch between applications. Apple was accused of copying the current visual appearance of that function from some software company. The function itself was invented by apple, as far as I know, but somewhere along the line of osX developing along came the "pop up" that highlights the selected application.
If this is what you were questioning and you won't take my word for it I can dig up a link, but only if it is really needed
Anyway, I'm happy either way, keep the cool features coming (even if they are ripped from someone else)
