The GratzCycle addon for World of Warcraft, Mists of Pandaria Classic allows players to cycle through preset congratulatory messages in guild chat using the /gratz command. It includes a configuration interface, accessible via /gratz config, where users can add, edit, or delete messages through a GUI in the Interface Options panel (or a standalone frame if Interface Options fails). The addon stores messages in GratzCycleDB, a SavedVariables table, ensuring persistence across sessions. Key features include:
- Sending the next message in the list to guild chat with /gratz.
- Managing messages (add/edit/delete) in a scrollable list within the config panel.
- Robust error handling and debug output to diagnose issues, such as ensuring GratzCycleDB.messages is a valid table.
