Yes, I know exactly what you mean. The user avatar/info area is too small, making it blend into the content. This is how the reddit mobile app does it, but I must admit it bothers me too. We will try increasing the avatar size in the full width layout. That will open up some of that space and make the break between the notes more prominent.
Thank you for caring enough to provide all this feedback!
The corners of a post were rounded too which really softens up the page, we need rounded corners please.
Please keep your new appearance settings but just give more options to adjust by the user or to set the old style appearance with user options to change that too.
I was also thinking after you said a twitter or reddit style feed, well i want a Nostr style feed. I say this in the same context as the meme "What if we used 100% of our brain, well we would cross post to twitter and not the other way"
