Hi there,

the mentioned mod works very well.
It allows the user to create custom dimensions while in the game.

Mapwriter recognizes them and tries to generate the map files.
But also it keeps the files from DIM0 loaded and the result is:

it switches the map between the newly created dimension and DIM0 back and for.

Is it possible to add support for custom dimensions?

Further I noticed, that in the mc saves/mapwriter folder that MapWriter stores the region files for DIM0 in the main folder, while all other region files (ex. : DIM-1) are stored in a subfolder.
Same behavior for the image files.

BTW: the mentioned mod is open source:
Here's the link to it's Github repo: https://github.com/lumien231/Simple-Dimensions

i'll see what i can do
