Server Groups/Sub-Communities/Sub-Servers

There maybe better ways to make of it instead of the "1 + n deeper layer of categories" when it can be something of this Then making channels beneath it? not sure, it can keep similar channel layout except make it a group within servers. image image Not my platform but its a suggestion that maybe useful for fluxer to make it a bit better, and that it can be optional to make a "sub-server" type system.
