Be able to pick what axis should be used to scale my prototype/mirror

Right now, Figma uses the frame’s width to determine the size on the device’s screen you’re opening it on. As there are occasions where someone designs an interface for a product that doesn’t have the usual screen ratio, it would mean that skinnier frames get a part of the content cut off.

So please, dear Figma team, allow us to choose what axis it should pick for resizing to “fit”.
