...and it was really quite simple to do! Sherlock is pretty stupid: all
you can do is click on him to specifically google the current tab's website.
So, if you find yourself adding "site:example.com" to your Google searches
often, this should be a nice shortcut.
Here's the MIT-licensed code: https://github.com/gnarmis/sherlock. Download
the install package here; double-click to install. I've even put this
puny release on the Chrome Web Store, but it's not showing up yet.
EDIT: this link should work!
I'd love some comments/feedback! I'd rather not spend my precious winter break
on a doomed hobbyist project...
