I've been looking around now, I've noticed that there isn't a map marker creator mod. I know Jaxonz Map Marker exists but that doesn't function very well with what I'm talking about. So I'm someone who isn't that technical at modding and could make map markers via CK so if someone can make a mod like this bless you! Please let me know if you've made the mod and link it to me and I will download it and share it
IDEA OF IT
So you would either have a spell to mark a location or if it's used with MCM then a hotkey. It would then open a menu like the image I attached.
Once you are done you would press the "Finish" button then your map marker will appear for that location, and you would also be able to fast travel there.
Hopefully this post is seen and made
