Is your feature request related to a problem? Please describe.
A clear and concise description of what the problem is. Ex. I'm always frustrated when a player can use commands with a colon, I would like to block /citizens:npc ( in the command blocker .:. does not work, and : does not block the command above.)

Describe the solution you'd like
A clear and concise description of what you want to happen.

Add support for regular expressions and a detailed description of the plugin's functions. I couldn't find it on spigot or on the git-hub.

Add regulars please). The plugin is great, without bungee cord support I would have drowned myself(
