I've raved about Launchy in the past. However, I had not upgraded in a few versions, at least ,until today. Then I saw version 1.0 was out with a host of amazing features.

New features (commands in parentheses):
- Search Google / Wikipedia / IMDB / etc from launchy (google TAB search term)
- Imports Firefox Quicksearches and Bookmarks (quicksearch TAB search term)
- Built in Calculator (+ - * / and parentheses only)
- Browse folders on your desktop (driveletter:folder/path)
- Launch web-sites (type www.random-tech.com)

Download it today. Launchy is probably my favorite piece of software available today (even over Firefox and RSSOwl -- though, you should use those too).
