Allow Portrait Mode Presentations
Currently presenting a slideshow in portrait mode forces you into the "Presenter View", however it would be incredibly useful to be able to exit this presenter view and simply view the slides full screen like you can in landscape mode. An example use case is presenting an app prototype, where showing it only in landscape isn't feasible

I would love to be able to do these kind of slide presentations fullscreen, I want to design some templates for Instagram Stories, and Powerpoint slides in portrait mode are the perfect canvas, I just need them to be fullscreen in order to be recorded and then shared.
