Allow to import contact groups

Groups (=Labels in Cozy) are not imported, which is very annoying. I have around 2500 contacts in ~50 groups (a lot of contacts being in more than one), and I can’t afford the time to relabel everyone.

Hi, any progress on this? This is really the last thing (contacts) I still use Google for, because of this issue. I would be really grateful if you manage to fix this so that I can definitively remove my data from Google services. ;)

Hey @ArchangeGabriel, we currently have no immediate plans for this feature, but rest assured we won't forget it!
We will keep you updated when we know more about the "when".
