Features include:
- uses Google Suggest when you search
- adds links to competitors ("Try your search on Yahoo...")
- rewrites links to point straight to the images in Google Images
- removes image copying restrictions in Google Print
- secures Gmail, switches to https
- anonymize your Google userid (disabled by default)
- removing ads (disabled by default)
- adds counter in search result (disabled by default) (NEW)

Just thought it was a neat extension.
