Package out to specific window dimensions

Hi, I’ve seen a few threads on how to get the Windows package to open in window mode rather than fullscreen, but nothing about dimensions. I’d like to be able to fix the window size to make a custom little app - think the standard ‘Calculator’ app. Is this even possible? And can I then set up a custom UI Widget at a matching size? Any thoughts appreciated!


Does anyone know if this is possible? It seems surprisingly limiting that users can’t input custom resolutions for the output. The Windows Surface my colleagues use are sometimes set to 4:3 ratio, but I can’t see a way of working to this in the Widget interface…
