My new favorite context search add-on! It's simply brilliant how you can have exactly the engines you want outside the submenu, and in any order. Plus the fact you have control over how the search tab opens (or uses current) is a huge bonus. Well done.
One suggestion I would like to offer is have a visual guide in the manage engines dialog showing what you have selected for each engine (like if it is set to site search, if is outside the submenu, etc.).
