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

Panels showing the 3 frontier shapes and the list with collections

Version 3

Big changes are coming in this new version. The features already implemented are Path as a new shape, Collections for organizing frontiers, and an API so that anyone can create a plugin that interacts with MapFrontiers.

The API is published as SNAPSHOT and its design is not yet finalized.

From this version onwards, Forge Config API Port is no longer needed.

Features

Vertex Frontier: A single polygon in any shape you want. Use the left mouse button to drag vertices. Use the right mouse button to open the menu where you can add and remove vertices.
Chunk Frontier: A group of chunks that you can add and remove individually with the right mouse button.
Path Frontier: A trail of markers. Use the left mouse button to drag points. Use the right mouse button to open the menu where you can add and remove points.
Collections: Organize your frontiers into collections. Make them visible on the map when you zoom out.
HUD: Next to the JourneyMap minimap, you can see which frontier you're within. You can edit appearance and screen location in settings.
Banner: You can assign any banner you have in your hand to your frontiers. It can be displayed on the map and in the HUD.
Permissions: In settings, players with OP permissions can change who can create, modify, and delete global frontiers.

Client or Server?

The mod is optional on both sides. It is placed on the client for the player who wants to see and use the frontiers. It is placed on the server so that global frontiers can be created (which can be seen by everyone who has the mod on their client) and so that personal frontiers can be shared with other players.

Current limitations

Doesn't support vertex 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.

For those using the older version prior to 2.0.0:

To create and manage frontiers you have to use a Frontier Book. When you open a book for the first time, it will be assigned to the current dimension and will allow you to create your first frontier. It also provides some data and an image.

FrontierBook

In creative mode you can find the book in the tools tab.

You can craft it with this recipe:

You can also craft the personal frontier book:
