This is for the World of Warcraft Classic version.

REQUIRES HandyNotes to be installed.

Marks the location of all dungeons and raids from previous expansions with the newer blue and green dungeon and raid markers that are used for the Broken Isles.

Please leave a comment or file a ticket if I've forgotten to include a dungeon.

Right-clicking on a marker will set a waypoint if TomTom is present and enabled.
~~Dungeons/Raids with any lockout will now show as gray, this can be disabled in the options (does not apply to Legion ones on the zone map, only continent or minimap.~~
Settings can be found under Interface -> Addons -> HandyNotes -> Plugins -> DungeonLocations

I've enabled localization for the configuration settings, if you want to help translate you can do so.

Let me know in the comments or by filing a ticket if a dungeon or raid isn't showing a lockout when it should. For certain dungeon and raids, a slightly different name is used for lockouts and I have to fix it on a case-by-case basis. Include the instance name and the name that shows in your list of lockouts.
