Right-click a dungeon in the Mythic+ tab to get routed to its entrance, intermediate portals and all. Left-click still teleports. Entrances are read from the client at runtime, so a new season never needs an update.
Keeps your GatherMate2 map icons but hides the proximity tracking circle, so nodes hand off to WoW's in-game minimap node when you get close. Per-node-type toggles, mining on by default.
