I’m levelling mining (for the stamina bonus and an income). At 400 now on my reroll DK. I use the SexyMap addon combined with GatherMate to get a HUD when flying around, and for overview of node locations on my maps.
The two addons are integrated within the SexyMap configuration.
The HUD is best explained with a video, so I put one together (narrated) to show you.
Because the HUD hides your normal minimap, I have a small zone map showing. Normally I wouldn’t use it.
An alternative minimap replacement is Chincilla, discussed on an unrelated post I had about FPS issues, if you want something else.
