Recently Quark Oddities (r1.5-140) added a new Enchantment Table GUI and function. Is it possible for compatibility to be added for this?

Currently the new Quark GUI will appear, but then after a couple of seconds, the GUI from this mod will replace it.

Turns ouf there isn't a simple way to do it. I would have to reimplement quark enchanting system by myself.

So the bookshelves that you add won't work with quark's system?

I didn't test that part, what was happening was that the GUI kept changing from Quark's GUI to a normal GUI, but it's been a while since I've used this mod. I think in the end it ended up working fine.
