Sorry about the minimum iOS version! I rely on various APIs that iOS 16 brought into SwiftUI.
The point you raised about "read later" started spinning some wheels in my mind. I really like that idea. Right now I have bookmarks, but that would only be the same workflow as you have with favourites. I'm now thinking up ways to make that "I'm finished reading this" either dynamic and/or manually initiated.
I'd love to take the "hide stories I'm not interested in" approach and pair it with the flip side, "send me a push notification whenever a story is posted that mentions <keyword>".
I've tinkered with automatic categorisation (with mixed success) before using OpenAI, which may help users filter out things that are deemed "sensational" or "political".
Thank you for this feedback. It really helps!
