Shut Up, Horseman!

Shut Up, Horseman! is a tiny, focused World of Warcraft addon that silences the Headless Horseman during Hallow’s End. It mutes all 37 known voice files associated with the character, including his speeches, laughter, combat shouts, and other vocalizations.

The addon does not mute general dialogue, music, ambience or any other NPC. It is enabled automatically after installation and includes a simple checkbox in the AddOns settings.

Control commands:
/hhmute on to silence the Horseman,
/hhmute off to restore his voice,
/hhmute toggle to switch the current state, 
/hhmute status to check whether the mute is active.
OR
/hhmute - to open menu and put check mark to make him silent or remove it ro return his voice.

No dependencies are required.
