[Edi]

As of the present, there is no modding capability. There may or may not be modding capability later, but we do not know yet. Other than one mention in passing, it has not been discussed because there is still so much work to do with getting all the basics done.

For example, there are still lots of legacy graphics and all of the classes don't even have a description yet.

However, knowing Johan, all hope should not be abandoned by any means. With regard to any possible future addition of modding, patience is required.
