Is there a way to collapse topics so I can see a list of topics and the first posts, without replies, in the main window?
I don't think there's a way to do that today, no
I also feel like I've never quite wanted that :)
Maybe there's something else that would also work? What are you aiming for?
I want to catch up on everything I've missed in the last week, but the topic title alone is not enough and the full thread is too much (since scrolling past a long thread takes forever)
ah yeah there's not a great way to do that if you want to catch up on everything, I guess
There might be a way to skip to the next topic
(i.e., you can click in the sidebar)

Opening a thread should take you to the first unread post in it, but then it is two taps to get to the next one (on Android): back button, tap the next topic title in the list
