Lollipop quick circle and WiFi calling topic

So I was wondering should I wait for the official ROM for my g3 or does cm12 have ways to support WiFi calling and my quick circle case? If so how? I want lollipop bad but I like having root etc. I use skydragon 1.1.0 that has root and still stock items on ROM. Also I have nova prime and was wondering could anyone recommended a launcher that looks more graphical and etc I like nova but I'd like to have a 2nd option.
