NAV filter by Attila Bakos

The addon makes the "Incoming messages" list of ugyfelkapu.magyarorszag.hu more readable by providing background coloring. It's based on the Chrome plugin "Clervice NAV szűrő" v1.2.
It's meant to help bookkeepers by making it easier to read the huge amount of messages they receive on this site. Please do not rely entirely on this plugin! The author cannot be held responsible for any damages caused by the use of this addon.
