I already found the laser_drill_ores dictionary and looked into the files, but had no idea how i should change them to set ores per dimension.

For Example:
Ores from a Planet should only be mined on that Planet.
Or if you mine in Aether the Ores from Aether, Overworld and Nether should be mined.

If this is already possible an entry in Wiki here on GitHub would be nice :)

Look at the file, there are examples for that.
