Hmm, this is a really interesting topic. Generally I've tried to stay away from game-specific implementations within the CLI interface itself so this could maybe be done with some sort of "linking" hierarchy.

I reckon this type of "server-linking" would require that the game config is already natively exposed to the CLI, so this issue can be worked on when #21 is closed.

Okay. Yeah the bungeecord server would probably be best thought of as a different kind of entity than servers. There are probably other kinds of entities that you could have in the future too, so a system similar to docker or kubectl could be possible here. For example:

wilfred server list
wilfred proxy list
wilfred logger list

Perhaps this could be implemented as an extension after #34 is implemented?
