With the QuickChat Addon,
you no longer need to type the /s, /i, or similar commands into the chat to switch chat channels.
Now you just have to press a button and you change the channel.
The buttons Guild, Group, Raid, Instance and ReadyCheck are only visible if you are in a guild, group, raid or instance.
You can move the chatbar to any position you want. Simply click on the left or right edge with the left mouse button and move.
A big Thx at KalitaAlexey for the settings Page.
The only problem is that when you uncheck the button doesn't disappear until you restart your UI.
