Panic Button Plus
The “boss key” has been a favorite hack since the earliest browsers: The boss walks in, hit one key and everything you were doing disappears. Panic Button Plus is the best boss key for Chrome.
It isn’t just for bosses -- PBP remembers everything. If you get called away from your desk and want to save everything open in Chrome, you could leave it running and pray nothing happens with your computer or connection; you could shut down Chrome and hope restore brings everything back; you could put all open tabs in one ginormous Bookmark; or you can click Panic Button Plus, or press a key combination you set in advance, and everything’s there waiting for your return.
