configure keys? Rated 4 out of 5 stars

Great idea!

But what about people who use a touch-pad, that hasn't a middle key?
Some options to reconfigure keys in a setting menu in a later version may be helpful...
(specially for getting a Google cache in a new tab for comparing)

@Kitsu:
"Full Reload" dosn' mean "Reaload all tabs".
AFSIK it means realod with bypassing browser cache and cache of ISPs. (_Everything_ directly from source page. - If the ISP suports this.)

BTW: CTRL+F5 woks in most Browsers without any plug-in!

This review is for a previous version of the add-on (1.0). 

Trackpad support is now available as of version 3.0.0. Hope you'll consider upping your rating!
