Universal Control for the iPad Pro

The eyes still think Apple should make a version of the magic keyboard, the Bluetooth one and the magic trackpad that supported multi-device pairing. I would also like to have the option to connect both a Mac and an iPad via Thunderbolt and switch the display and peripherals between them in Control Center. And then finally on Universal Control, why not make the Studio Display even more valuable and when I plug into it, I get the benefit if there's a Mac connected to it to accessing its drives and its ethernet connection for instance.
