Excellent Work on version 1.0.5 Rated 5 out of 5 stars

Just tested the latest version 1.0.5 with support for "L.A.R Grizzly toolbar-button-icons themes" it works and looks great. I'm glad that you took on the goal of fixing the border-less look of the toolbar buttons in small icons mode on Fx 8 and later.

Keep up the good work...
