Wow, great user interface, for every task a really useful description in the status bar area shows up telling you what it does. I'm running in a limited user account and for the following uses it doesn't require my admin password:

1. Show/hide invisible files in Finder
2. Cool hidden dock preferences
3. Run dashboard widgets on desktop :)
4. Hide desktop icons. I run Blue Skies screen saver as desktop background using Desksaver Plus Widget and Spirited Away to keep visible windows to a minimum. (All programs mentioned are free and available on MacUpdate)

This program does a whole lot more but if it only did one of the four I mentioned I'd still keep it around. Cannot comment on stability, only been using it for a short while but have noticed no issues. So far, so great :)
