# filters
Allows players to save and load chat filter settings with ease.
Allows players to save and load chat filter settings with ease.
# Warning
This addon overwrites parts of a packet that manages various sub-commands. Using this addon may keep you from being able to toggle those commands on and off properly. Things such as: party seek flag, auto-targeting, and similar features.
It is recommended to only use this addon if you are on a private server.
If you need to use this on retail, it is recommended to load the filter set you need and then unload this addon.
