Oh look, found another. Enchanting table is missing the little gemmy icon thingies that appear to the left of the spooky enchantment text. Not really necessary for normal use since the tooltip should also tell you how much lapis is getting used, but eh. I don't know why they're green when you power it with lapis though. Another color might be good if someone feels like it.

Don't feel bad about potions. I didn't know potions took blaze powder. Last time I played before this, you just shoved a bottle and a mushroom in the thing and called it a day, so I was really confused when it wouldn't work.
Should I continue posting these here or should I just send them to you directly in some fashion (email, discord, skype, pm, whatever)?
