I have the idea, that 3D Artists can detach Windows from the 2d at the side of the viewport into 3D for example on the side of a object, so you can use the viewport in the modelling expert mode, and have the Attributes aside the Object, so you can, if you need it, change the Attributes of the object. I think, this would be helpful especially, when it comes to rigging a model, it also would be cool, if people work in VR with Maya, so they don't have a HUD
