Let me show you with pictures when tapping on a comment on each app:
Relay: Expanded and collapsed
Sync: Expanded and collapsed
Official: Expanded and collapsed
Jerboa: Expanded and collapsed
See the way only the comments disappear on the 3rd parties with an indicator on the side to show comments are hidden? And on the official app the comment goes to a small gray preview of the comment? The way Jerboa works now is closer to the Official reddit app, but has no context of the comment, like the Official reddit app. I think it should either 1) change the behavior to be more like the other 2 I show, or 2) keep it as is, but add context to the collapsed comment.
I would prefer option 1 because that is more intuitive to me, but I think that is because that is what I'm used to, and not because it is the "right" way of doing it.
