7plus - Project Hosting on Google Code
"Written in Autohotkey, 7plus is a project which tries to make working with Windows much more comfortable by adding features to explorer, window handling, and lots of other small tweaks. For example it allows you to quickly upload files to an FTP server directly from explorer with a single hotkey, navigate to your favorite folders with numpad keys, keep windows always on top, etc.."
Adds some cool things to windows 7. Copy jpgs and txts to and from clipboard via right click, etc. Small download and small memory footprint.
