Pre-populates search boxes
Pre-populates search boxes on supported websites so you don't have to re-type your search term over and over again.
For example, Search Aid captures the last search term used on Amazon.com, so when you visit Ebay.com your term is pre-populated on the search box. The captured search term expires after a few minutes, after which it is no longer used.
The code is available on github, you can now add more sites for this to support.
