Are strangers going to come to your house for this?

I'm not sure what you're saying about the google searches either. Are you saying that when you're reading a page when you see something you'd like to explore further you highlight it, right click on it, and choose "Search Google for _____".

Since the page opens in the background you don't check it for a while. Then once you do start reading it you forget what the search was for?

I agree with your find bar idea, multiple find boxes would be very helpful.* Or at least an option to have one "find" query per tab (instead of one per window like it is now). I'd also like some more power in my searches finds (wildcards, "or" option, number ranges, etc.). The "Match case" option is nice and all, but I could use a few more options.

* I didn't read much of the Thinger page, does it have that option?
