Hi, i added a feature which make it possible to designers to work based on certain device size and then scale that render up to current device size if it is larger. I felt for need and came across this feature when i was working on a Figma template which was designed based on 1540px screen width, and i needed to match my sizes like fonts, column widths, aspect ratios and other stuff with that design and so i first used ResponsiveScaleBox with width 1540 but then i wanted to scale it up to my screen size without any empty borders. So by this feature, i could design based on the figma sizes and then scale up to my screen size. I hope I made my point clear, i'm not native English speaker
