I've already started working on "additional artwork classes" that you could freely define yourself (#49). I'm basically open to add more "static" artwork classes when useful, but this approach is more flexible (and would include support for "side art" as well). I just need to complete this work smile... no promise, but I'll try to do this in the next version.
