Turns the left edge of the screen into one large navigation button.
This is a port of the popular Firefox extension MileWideBack. The extension turns the left edge of the browser into a large forward/back button. This only really works if the browser is maximised, but it means you can slam the mouse onto the left edge then quickly close/change tabs, go forward or back.
Left click: Goes back one history item
Right click: Goes forward one history item (also can close or refresh tab: see options page)
Middle click: Closes current tab
Scroll Wheel: Change tab
* Tidied up options page. Now can bind page-refresh to right click.
* Added options page, now can choose scroll behaviour, right click behaviour
Bugs: The extension doesn't seem to work on the Google Chrome extensions site, on new tabs/downloads page/extensions page etc. This is a security feature of Chrome, I can't do anything about it.
Note: The theory is from http://en.wikipedia.org/wiki/Fitts_law for those interested.
