I've recently discovered non-destructive editing in Photoshop. I'm now carefully building my images so that each layer or adjustment layer can be independently edited without destroying the original content. There's just one annoyance, I like to work on the highest resolution 16:9 ration I can but I need to export as a 1080p image. Can I do that without flattening the image and resizing it? This gets rid of all my careful non-destructive work and I can only work around it by saving a copy of my PSD, which is annoying.
