One missing piece is the Y-levels. Recipes can have a kinda large Y value range & the default is about 5 more than the world height. I expect a lot of people will try manually dropping items from world height and having it not work since it's not high enough, it needs just a few more.

Since its Botania I don't want to just expose Y values directly but I think i might have to. Possibly on tooltip hover or something.

Other options to float are drawing particle lines from items that are close to the skytouch min Y but still below it.

Also: consider the default max Y. It's enough for one mana burst with Messenger Influence. But is that very creative, not really. What is the highest I can send an item over the height limit with only Botania?

Meh I think it's ok tbh
