Thanks for leaving a comment!
I'm currently working on adding the measurement tool (which should be ready in a few days). Configurable sizes for markers is on my todo list. I was debating about having some sort of road tool, but I figured it would be easier to draw the road on the map before uploading it. However, borders is one thing that I would like to have. Then you could draw the borders of realms/ kingdoms/ factions in real time as the story updates.
