Collapsable server channels.

So, my issue for the desktop version of Discord is how you can't really shrink down the window to a smaller size. This, I think is due to the fact that channels are permanently locked into the side of the window next to servers. What I propose is making it something like the "people" section. So, you can close the channel bit when you want so that you have more room to chat, without any extra information stuck on the side stopping you from shrinking the window. 

I don't know if that was explained very well, or if it was already suggested, so sorry if I did anything wrong with that.
