Leap is a combination Spotlight, Bridge, Finder, and more. The Finder on OS X is slow, cumbersome, and limited. The Finder search interface is very cumbersome. Leap shows you all your files and more importantly - where they are on your computer. No other tool does this. Works great for images and PDF's, too. Leap does not force you to put documents in a special place, it uses no databases. Just see whats on your hard drive.
