If I have a "test" lens attached to the "!test" bang, and do "! !test example", it redirects me to a website, but not one which is in the lens. I'm guessing it's just taking me to the first result of "!test example" being searched literally? Could the Feeling Lucky bang take into account lens filters?
It'd be useful for users who want to visit the first result of a search term filtered with their specified lens settings.
