- Comment width doesn't get narrower no matter how deep in the comment tree you are
- You always see the parent of the comment you're currently reading
- Swiping allows you to move in and out of subtrees with animated transitions that you fully control
- You can easily skip subtrees that don't interest you by scrolling
As a result it's easier to maintain the context and to keep track of where you are in the discussion tree. The app is fully featured, it does all the things that you would expect it to do, and there's extra: custom boards, search, in-thread search, anchors, reading list, recent items.
