LoggerHead is a an automated combat log enabler. It allows you to select via a simple GUI interface which Zones and Instances to automatically enable for logging. Works for PvP/Arenas(For real this time)!
LoggerHead has a LDB module for those running a Data Display. Left Click toggles logging. Right Click opens configuration screen. Enjoy.
New in version 4: Loggerhead dynamically builds dungeon and raid information instead of relying on external libraries. What this means is that your configuration menu will *ONLY* show instances and difficulties that you have discovered/entered. Better yet, it also means that LoggerHead will work with new dungeons and raids without having to be updated!!!
