Before one of the recent updates, you could just enter "a" in the taskbar if "a" was stored as your amazon.com search field, and you would get the site with an empty search box. Nice!

Now entering only the search engine letter(s) with no actual text after it always defers to the default search engine, i.e. searches "a" on google or whatever.

Somewhat less useful IMHO.

Could you guys switch behavior back to how it was?

Would be very cool! Thanks, Gundolf
