It's fair. But it doesn't override conflicting hotkey. Nor does it show a warning. (eg: ctrl+shift+r)
Also it lacks an option for a verification dialog to prevent accidental restarts, which is a desired feature for restarting just as much as for exiting.

It's cool. I only miss simple reload dialog. I keep accidentally relading the browser, most of the time when I want to press ctr+alt+t for tab duplication. I got rather used to the hotkeys as most users so asking before restarting would be nice.
