This plugin (Command Simplifier) can take commands for bungeecord like /server {servername} and make it just be /servername.
Server owners can use it to simplify any command though

If you wanted to make a command to /kill {playername} you could just make it so that you do /k{playername} or something along those lines. This is strictly a utility plugin to make things easier.

The only bungeecord support it has though is /server, it cannot do things like /alert and other bungee commands.

This is a working example of the config
help:
- help
- h

factions: (name of command)
- server factions (real command)
- factions (simplified command)
