Hey! Love you plugin! I know it's beta and therefore not supported etc etc, but a heads up that the icons in the admin bar disappears in 3.5-beta2-22352 when using this plugin.
Guess it's this line in the CSS that does not work:
The "../" part won't work because the css is located at different location when using and not using BWP. And I guess it also could be because the admin css is called admin-bar.min.css and not only admin-bar.css anymore.
