I'm not one of those who overly criticize the Finder. But there's one little thing that annoys me to no end : Let's say you're looking at a long list of unnamed videos in the Finder. You hit spacebar to get Quicklook. You want to see this video full screen so what do you do? Hit command-F of course, the now universal shortcut in Lion for the full-screen mode. But not so in the Finder...Hitting command+F in the Finder activates the "Find" command and the Quicklook window changes to a huge "Smartfolder" icon, leaving you with a blank search window behind! Ok so you've made a mistake, let's go back...You get back to the same folder alright, but your selection is lost! You have to scroll down to where you were and hope to remember what was the file name of the video you were looking at (If I could identify the file by name I wouldn't have used Quicklook!) Anyway it's a pretty stupid and un-Apple-like interface quirk that I would've hoped would be fixed in Lion especially since command-F is now standardized as the full-screen shortcut.
