Great addon, but is it possible to add an option to move the countdown timer to somewhere outside of the web page? Say, within the toolbar button, or the options page. I want to limit my browsing to a few hours a day, and I don't want the timer to be visible on the page if I only need to check it infrequently, but as far as I'm aware it's not possible at all to find my time remaining if I leave the timer disabled. Other than that it does everything I need.
