MapFrontiers

This mod is an addon for JourneyMap that allows you to divide the map into regions and assign them names and colors.

You can create frontiers within JourneyMap's fullscreen map using the buttons on the right.

For vertex frontiers, use the left mouse button to drag vertices. Use the right mouse button to open the menu where you can add and remove vertices.

For chunk frontiers, use the right mouse button to add and remove chunks.

You can edit the mod settings and change who can edit, create and delete frontiers. Default key: F8 (I accept suggestions for the default key).

If you can't edit the groups or actions it's because the OP didn't give you permission on the server.

Current limitations

• Doesn't support frontiers that intersect themselves.
• JourneyMap moves Minecraft effect indicators with the minimap. MapFrontiers doesn't do that so they end up in front of the frontier indicator.
