"or maybe a way to browse original inputs" - You can see a timeline of the sources if you tap/click on any of the items in the feed. Guess that isn't obvious enough.

"chose different feeds" - If you click the filter button you can choose multiple categories like tech, business, social media etc. This feature needs to be more obvious too. Or were you thinking of something different?

I like the idea of bigger cards when they have more sources. Don't think it would work well on mobile but certainly a tablet or larger.

Thank you again for taking the time to respond!
