Feature Request: Server Grouping instead of List

Currently servers are one extremely long single column vertical list.
This gets very confusing if you follow many different people.
To make this more user friendly allow users to create groups where you could just drag the server down into the group.  For example: News, Gaming, or Tech.

On the PC version of discord you can currently drag one server over another.
It looks like it adds them into a group, but instead pushes that server to the top of the list.

So you have the basic UI already implemented.
You just need to allow those servers to be placed in some ArrayList of servers for that group.
