They are still usable it’s just that you won’t see them. If you have played Minecraft PE for a long time then you’ve probably learned by now where the buttons are and don’t need the interface buttons to help minecraft circle creator. It’s a really simple change but it definitely makes the interface more clean and simplistic.
The button features still works it’s just that the graphical user interface for the buttons have been removed. This is what the interface looks like without the resource pack enabled. The buttons take up quite a bit of a space and over time gets kind of useless since you probably know where to press anyways. Note from creator: I’m trying to hide the inventory button as people requested, but I can’t. Maybe someone can help me with it? And for everyone: You CAN’T do this in settings! Screenshots but is something completely different.
