Alternatively, can an article be part of more than one collection? The reason being: some articles belong to more than one category. I have some articles on motion design and animations for the web and they span the spectrum from UX, to Interaction Design, to Motion Design, to React.js, to Front End Web Dev. It’s impossible to categorize them with the current way collections and tags are handled. When I try to create collections and add them to multiple collections, they just get removed from the old one and added to the new. I want to have them appear in all the relevant collections for easy retrieval later. The other way that would work for me is smart collections where I can set some conditions based on tags (iTunes style).
