Search: Keep input and unify history
Assume I'm searching for "Yukichichibu onsen" in Japan (didn't make that up ;). I first try Google, but no result. So I switch to Geonames (or search address). Argh, my input is gone - history to the rescue! I type "yu", but nothing! Both searches store different histories :(
I think it's a very common usecase to search for something in source A, and then B, and perhaps C - so it would be very helpful if the input line would be kept when changing search (as long as the dialog is open) and if all searches had the same history, don't you think?
