So I was looking into starting a project to build a desktop web app to help build Zooper widgets. I was able to save a basic widget, export it as ZIP, and I see all the JSON files. My only question is what is generating the hash name for the json file. What is its significance? I would like for the web app to be able to create new shapes and set its properties, but I don't know what I should do to generate the JSON file names.
