Yes, I've modified some of the mappings for Matroska video MKV with Mp3tag v3.29. This was motivated by various reports regarding compatibility with Windows Explorer, where some fields were not displayed for MKV files. Here are the details:

I also think it'd be great if you could somehow implement user-defined mapping functionality, including the target type levels, for Matroska tags. A mapping I'd particularly like to add, which I think would make sense to have as a default, if it could be done more quickly that way, would be from Mp3tag's TVSEASON field to Matroska's PART\_NUMBER tag at target type level 60 (T=60). If I create this T=60 PA…

I have to think about on how to proceed further. One easy way I can think of is to revert the change regarding `TITLE` and have it mapped to T=30 `TITLE` in Matroska. `ALBUM` would be T=50 `TITLE` in Matroska.

But this would revert parts of the consolidation process we went through over the past month. Also, there would be new inconsistencies regarding artist and subtitle target types.

What do you think? /cc @RobertM
