Notify when a block or player is exceptionally laggy.

Many players on my server end up lagging the hell out of the server without realizing it.

It would be really good if observable would be able to send a message to a player when they are laggy, or a block near them or in their claim is laggy. The setting should probably go in the server config.

This is a fantastic idea, yeah, it would be great.
