I just noticed some new options when you click Show Options... in search results. You can now 1) search in pages that you visited/not visited before 2) show more / less shopping results. I think that both are actually quite useful features.

I can't find any right now, but sure looks like they'll be merging all Google search engines like Google Video, Froogle, Blog Search and Groups.

This appears to be a good contribution to us by GoogleLet me try it

I've been using Show Options a lot lately regarding the Treaty of Lisbon and I love it
