I always use one of Ombeys maps, next to the computer for easy reference or have the pdf open in the background for when I navigate the different regions.
Remember to update your 2D map !
I will see if I can gather different navigational links in one post and comment on thier strength and weaknesses.
Ombey’s 2D maps are better than sliced bread! I always have them open on my second monitor for quick reference.
