Hi @alexzurbonsen - if-models is actually removed in our latest refactor. The only change needed here is renaming if-models to if-plugins.

Okay, makes sense to me. That also was what I did at first, but then I thought that it might be nice to cover legacy models as well.

But I can remove that of course.
