Could you add something?

Hello
Would it be possible to add the following to the CuiData? Then you could make the button background look 1:1 like the originals. 
I would be grateful

."Sprite": "assets/content/ui/ui.background.tiletex.psd"

And one more thing.
You can hide buttons when you open boxes.
Would it be possible to hide buttons when you close the inventory and show them again when you open the inventory? That would be really great, I would even be willing to pay extra. I hope for an answer. 

Possibly in future
