Design for one Platform export for multiple platforms (Example: iOS icons/designs to android sizes)
We do design in iPhone 5 size that 320x568 and we have script for illustrator, which will give export GUI, where we can select export size options for both iOS, android and web sizes. This way we don't have to design icons separately for other platforms. Have attached screenshots for reference, there you can see option to set base frame size used to design this will do the calculations in background and will export scaled icons for other selected sizes.
Under Adobe XD you can create preset exports. iOS, Android, Web etc. However this is very limited. It requires either one file per export type (iOS, Android etc.) or selective export of single elements/artboards. This fragments on the one hand the workflow on the other hand one does not have control over the export and traceability at a later time. Sketch solves this very user-friendly without being complicated. So if another user has to do export there is no history what needs to be exported.
The export is usually one of the last steps in a workflow of a Designer. This should be as clear and simple as possible. At the moment you have to export XD for the different media individually, iOS, Android, etc. If there are changes you have to export everything from the beginning again. Ideally you should export everything predefined with one click.

I upvote thsi one, sometimes we create one design for a feature that will be on multiple platforms like both Android and iOS but for now in order to make correct icon formats for both platform we have to create two separate files and we have to select on both a different platform to export at. When in fact we could make all platforms we want available in a dropdown once we open the link and export to whatever format we want.
