Mod idea that I wonder if anybody has the know-how to help with

a mod on the map to pull the global coords of your portals and show the portals on the map view, and then drawn some stylized lines between them indicating which portals are linked together. seems like it would be relatively easy to do, but i have no experience with C# or the assembly structures of valheim. I know that the coordinates and portal names have to be easily accessible SOMEWHERE… but then how to pull them and then mark them on the map is an unknown.

Wondering if somebody might like to help me out with this. It seems like it might be a good little project for me to learn a bit more about how to mod valheim. I've been messing around with the configs for stuff like Valheim Plus and others, and adjusting them to my liking (for stuff a bit more complex than just messing with sliders in BepInEx manager or whatever). but I haven't actually opened up any of the assemblies or tried to make my own .dll plugin.
