Photoshop now has a nice feature you can right-click on an Artboard and choose "Export As.."
Once you do this on the left side of the screen you have the ability to add multiple sizes for scaling with the appropriate ratios and suffixes.
This is a game changer (and something that Sketch does really well). However, it is very annoying these export sizes cannot be saved and reused over again. They persist for the duration that the document is opened but if you close and reopen your PSD they are not saved.
Any ideas on how to make these export preferences persist? We are constantly creating copies of Artboards, changing a few things and re-exporting so this would save us a lot of time.
