Please describe the new feature or change.
Pretty much just adding Polymorph to your maven so that other mods that add their own GUIs with a crafting grid can add the button to them.

Please describe why you want this feature.
I have a backpack mod for Fabric that adds a crafting grid and overrides the vanilla survival screen with its own when wearing a backpack, and I want to ensure most things are available through it.

I'll do this eventually, but I should mention that the API and such necessary for other mods to add the button themselves is not at all ready for use yet.

Can you link your mod in question? Preferably I'd like to look into it and add compatibility for it on my end, which in turn helps me develop the API as I workshop the best way for other mods to interface with Polymorph and add this compatibility themselves.

Ah, alright. The mod in question is Cammie's Wearable Backpacks .

Im working on a 2.0 update that'll make it a lot more useful on the go by giving a 3x3 crafting grid in the inventory when a backpack is equipped, which is why I wanted to give adding compat a go
