I'm an avid user of search engines for quick translations during language classes.
As I quickly search new words over and over, I often need to cycle back to previous definitions, and having one place to do that would be awesome. Even it's just a session history or something ephemeral.
Especially since now even using the back arrow in the browser won't work (and sometimes produces weird in-between results when you realize your mistake and cycle forward in history again, like giving you the last 'input language' phrase but the first translation result - sorry if this is kinda piggybacking a bug report on this).
