I've been using this for years now, and though I have stuck with ver. 4.3.7 because it seems to be faster on my G3, I can totally recommend it as a must-have. Spend some time going through the documentation and playing around with it and you will be amazed at what it can do: open apps and folders, bookmarks, control iTunes, look up in Google, Amazon, etc., all from a tiny bar. Have tried similar freeware but keep coming back to this. It helps to peer under the hood, though, to really discover all the uses.
