I found a minor flaw in the Stormdark UI that you could fix. I noticed it while playing with the Magic Storage mod.
When I switch to the section that shows all the possible recipes in the game (not just the ones I have the resources to create), the resource pack is missing an additional background texture for the item's box that lets me know which item I can create now and which one I don't have the resources to create.

I'll attach links to screen shots where you can clearly see how it looks with and without resourcepack.
I would be extremely grateful if you can fix this problem or tell me if I can fix it by myself!
