I still much prefer the Damus view with tabs. Uncluttered UI is better than stuffing everything into one screen just because you can.

How do I know what post those reactions are to?
Because you tapped the numbers at the bottom of the post you’re looking at.
Oh. This is for a single post. Damus has no notifications feed?
So, you have to click on each section to see who zapped and each reaction? Sounds like a click too far for me.
And why does it display people's about info and follow button? I am not there to follow people. I just want to see how people reacted.
This is weird.
But have you asked your users what they prefer? Remember, it’s not just about what you think.
And I do use the follow button on my reactions. That way I don’t have to add another tap to get to their profile.
It was in the very early days, but we did.
Notifications tab is not the mood for follow and detailed info. This is more for a regular feed, when you are in the "get more details about this post I just saw mindset". On notifications, you already recognize most of the faces. "It's all duplicated". There is no need to explain or occupy more space than needed.
Organically, in over 100k downloads, no one has ever asked me to add a button to follow in that page or display the about info, which should speak volumes about the need since it's one of the most used tabs in the app.
