Dynamic scrolling viewport height based on screen size
Currently, for scrolling artboards there is a fixed-position dotted line that defines the height of the viewport in the interactive preview.
For desktop web sized artboards, I'd like the position of the dotted line to automatically adjust dynamically so the prototype fills the full height of the user's screen. For example, on a laptop screen the scrollable viewport might be 960px tall and when the same prototype is viewed on a desktop monitor the viewport might be 1200px tall.

YES, please. It is absolutely necessary to be able to view these at full screen in prototype preview mode.
Oh this would be great. When I'm presenting, I just want it to look best on the display, and I might not know what that would be before I begin the presentation. This would make me not have to worry about it. Basically, it would run the prototype at full width and then it would automatically apply the viewport height as needed to fill the height of the screen.
