Hi there FishTank,
Thank you for the reply. So, as the situation with the minimap stands, adding effort into new additional capabilities for that system may not be worth the outcome.
Taking a step back to look at the current system and managing it on a broader view, I would think it more feasible to look into ways to make the adjustments / changes of such a minimap system more visual and simple to setup.
By this, I mean changing out anything that requires knowledge of JSON with a graphical user interface to add/edit/remove map markers, map regions, map worlds and so forth.
Of course, the interactive minimap will - to my understanding - never become the only minimap that we offer, but is a supplement to the static one.
