Add a feature to draw a border

[C1sW0uth]

Hey man love the app :D You don't know how much you had helped so many players out there.

Would you mind adding this feature when you can input the world border on the server/world we play on to see which structure/biome is accessble within the confine of the world? I think this feature would be awesome and super super super useful

Something like this
