This idea addresses how we can have longer pages beyond the current artboard dimensions without manually resizing.
Artboards could actually be just a viewport. You could double click on a given artboard to open an expanded canvas.
In the crude example I've uploaded below, I can still keep all of my screens aligned as I have been. When I double click on an artboard, the canvas is expanded to show I have much more content on the page. Perhaps the rest are dimmed to emphasise where we are. Think isolated mode in Illustrator.
This would keep the best of the current paradigm of lining up our screens while allowing us to have long, scrolling pages.
This is indeed completed. We have a few additional enhancements to this feature that we’ll be adding in an upcoming release including a property inspector addition for scrolling giving you more control over your viewport and an artboard’s ability to scroll.
