Export to nested folders
The ability to name artboards and assets with some criteria (for example, a forward slash: "ARTBOARD1/IMAGE2/iOS/BACKGROUND") which would automatically generate nested folders upon export.

Export 2X and 1 X images separate folder for easy access. 1x images in a folder named 1x and the same as for 2X images. This will make the developer access or organize images in an easy way.
