Hey,
At GUADEC 2010, Matthias asked Richard Hughes and I to help with gnome-
control-center's port to GTK+ 3.x and update all the panels to the new
control-center shell that Jon McCann had been polishing.
Skip forward 7 years later, and I'm mostly doing patch reviews for
features and redesigns done by others, along with being the person that
rejects adding new options.
