Pretty cool plugin! Like the other review says you're missing the /ec and /invsee, but either way, I think you could improve on not using static since they're unneccessary. I'd use dependency injection. If you wanted to, you could just make a console logger utility class.
Good plugin, but you uploaded the wrong version (it does not have /invsee or /ec). You should use ChatColor.COLOR instead of the § symbol. You're still learning, but I can't wait to see what you come up with in the future! Welcome to Spigot, and good luck!
