TL;DR
Let us make our modded GUIs draggable like vanilla GUIs.What ?
A simple boolean in the Lua API that would let us toggle if a GUI should be draggable or not. To see this in effect in vanilla, boot up the game and drag around the main menu or your inventory.Why ?
I think it would help make modded GUIs feel more at home with the vanilla ones, as well as help players keep their screens free of clutter and more organised.It shouldn't be too hard to implement and it would be a very nice feature to have.
