Very useful new feature proposition !

Hello the discord team! I would have a proposal for a new functionality which if it is fine-tuned could be really appreciable.

The idea would be that as for discord servers, we can sort our contact / friends / group into categories.

I hope that my proposal will be heard because it would be really useful if this is worked out, because over time we accumulate a pretty huge list of groups and contacts which are just organized by "recent message", this which is not very practical.
