solution and I'm very interested to see how you continue to iterate its development going forward.

Looking at the roadmap I do see one of your "Planned" items is API/Webhooks. To my mind, that is perhaps the key to unlocking the full powers of Stacks, because savvy users will then be able to do things like mirror their actions in other databases, tailor data extraction for use in other functions like content production and triggers based on the addition of bookmarked items that contain specific keywords.

Along those lines, I did find on the Roadmap a single vote item for RSS Feed. That's a killer feature if you created the ability to segment into discrete RSS feeds based on keywords, tags or sources. If you had that capability combined with the API/Webhooks Stacks could become far more than a repository, but a data hub worthy of those subscription fees that will drive your MRR.

For inspiration on RSS sophistication, I suggest looking at InoReader which is a company that has built out connective/automation capabilities suitable for enterprise users far more than the average RSS Reader app on the market.
