I was suprised the Switch didn't support this mode of operation in the first place tbh. In this mode, it's simply a more powerful WiiU and could support asynchronous gameplay, maps on second screen etc that the WiiU did so well. Chronically underappreciated features in my opinion and I'm glad to see it returning. Now if we could only get the original version of Breath of the Wild where the tablet was the Sheikah Slate before it was all ripped out to support Switch, that would really be something
