There are two features that would make Shopify's CDN (Settings > Files) more usable. As of right now I have many different files in there for different purposes and they're all mixed together. It's extremely difficult to find what I need:
Folders - This would be amazing. Would make organizing files for products, blogs, and other objects so much easier.
Renaming - Why can't I rename a file after I upload? I have to delete it and re-upload it with the new name.
