There was at least one other comment mentioning this: the possibility of making everything on the screen more compact. Everything takes too much space at the moment and I can't really get a good view of a discussion "at a glance". This is on desktop, haven't checked the app yet. Something at least as compact as old.reddit would be awesome. RiF was the golden standard for me in this sense, just pure discussion, using the entire real estate of the screen. Would be amazing to have that option here. I just checked, and I can literally see more words on my phone on RiF than here on my 1080p laptop screen. I know this is all new, so I don't wanna complain, but I feel like this is something many would agree with.

In the same vein, it would be nice to have the option of hiding all avatars, the user name is enough for me.

Oh and another thing, even though everything takes so much space, the "border" between comments is somehow not visually satisfying. Those lateral borders don't really help in my opinion. If they would extend to reveal the parent-child relationship between comments, at least they would have a function.
