EasyGameMode

With this plugin you can change your gamemode with just typing /gm in the chat and the number of the gamemode, or the name of the gamemode.
This plugin will help you save your time since you don't have to type anymore /gamemode all the way in the chat, just /gm!!!
For example you are in gamemode 1 and you want to change it to survival, now you can do /gm 0 instead of typing /gamemode

As the image shows I have changed my gamemode to 1 to 0 by just typing/gm 0

In this case I change my gamemode to 0 to 3 by typing /gm 3

In this case I typed /gm creative and changed my game mode to 1
