Here are my suggestions
1- Add ability to have different languages. The feed should allow having one language or more and move between them or mix them
2- It is better if feeds with different languages keeps their our json file for contributing to be easier but build curated one automatically for them
3- This currently does not support RTL languages (or content languages in any of them)
4- It is good if the user can ban certain keywords because of the news fatigue about them. I might want the tech category but don't want to hear about LLM news
5- While the diversity of feeds is good in general. Sometimes you would want to block a certain website feed. Kite should support this in some sense.
I understand that this might be beyond the envisioned view if it as generic news app but I think it should be more personal.
