I use humanity theme because of its icons and colors; nothing more. Thus I use theme customizer for systemwide font setting and other stuff. As I wrote the widgets I use are my own - I mean I wrote them in python. I gladly share them but I need some time for that as they were written for my needs and the only way you can configure them is to manipulate the source code (not that hard to do that though). So before I share them I would like to write them as a user-friendly widgets...
