any chance for latest snapshot support? i really want that mod for snapshots since they added a lot of technical stuff

I'm not planning to regularly make versions for snapshots. As for current snapshot, maybe this weekend.

if you're gonna do that please add support for entity tags

If you mean entity NBT tags, they are supported

Also as I tested, 1.19.3 version works fine with newest snapshot (23w07a). It has some problems with detecting exactly what are types of tags for these new "display" entities but this is caused by a general imperfection in detecting types and it will be improved in future versions.
