Allow Classification and Grouping of Servers in a Tab/Folder Style

Simply put, it would be awesome to have the ability to classify anb group servers with some way to manage them. Thinking like a pop-out style folder system on the left where servers normally go in a tab style. Then notifications for servers in a tab not expanded could then show up on the tab, and when you expand it you can see further in. Also having an option to toggle which servers in a tab sort of... pop-out when the tab is not expanded to show it has unread things. To explain, picture this. You have servers for friends, servers for communities, and servers for getting help with bots, etc. On the left side of Discord is a tab for each of the categories you've made. You've got some unread stuff in a server in the support tab, so it's lit up to let you know. The communities servers, someone has ping you in one so it shows up with that little red 1. Friend servers though, you've got expanded to see them all like normal. Oh, now there's a message in that community server you really like, so it's tab now shows the server icon letting you know there's a message. As someone with a lot of servers for various reasons, I would love to have an option like this. I'm a part of several servers just for bot support that I rarely go into and would like to sometimes hide while keeping my active servers easy to see. This is where a tab style grouping system would be amazing.
