Even if so, it would confuse new players not familiar to the plugin and not knowing what's happening to their blocks.
It won't be added. As of now, for someone at Z mine, they can make between 1-3 tril every 10 minutes. If you never needs to stop mining, you would be Maki about 15-30 tril, or more every 10 mins. No support. Too overpowered and would destroy the economy.
Don't slate us guys, nothing has been officially announced. Auto-sell won't be added though. That just ruins the server.
