Love this plugin. Might you be able to reduce the size of the Clear Cache button in the admin toolbar?
It doesn't fit in the height of the top toolbar. It overlaps into the page, sometimes obscuring page content, and other times causing the admin toolbar to wrap onto two lines (also obscuring content). I know I can write some CSS, but I install this plugin on sites weekly, and I've long wished it would just not look ugly after a fresh install.
