Feature: Add specific channels to a "favourites" tab

I was talking to a buddy the other day and had an idea.

I know a lot of people are in many discord servers, and I know a lot of those people probably really only check 1 or 2 channels in those servers. What if we could take the channels we want to use the most from each server and add them to some sort of “favourites” tab? This would save having to go through a gazillion servers just by having what looks like an additional server at the top of your list that you go to and BAM! There's all of your favourite places to be!
