I don’t know if this ever made it to a roadmap for the product, but it should be considered.
There are a number of new tools out there focused around note-taking and organization heavily used in academia I’m sure: Obsidian, Roam Research, Notion, LogSeq, Mem to name just a few. I see more and more tools integrating with Zotero, primarily because they can. And it’s the first time I see people switching back to Zotero simply to have the ability to more easily integrate with all tools facilitating the thought process and the research.
I would take a good look at what the LogSeq and Zotero integration look like for example to get a better understanding of how people hope to use products like Paperpile. Starting around 7:55 of this video: Integrating Logseq and Zotero: A great combination for academic writing - YouTube, you can how, with the /Zotero keyword, the user can connect his notes with a paper and its annotations.
