Just one small gripe - the swipe from left edge feels a bit finicky, when swiping on the either the posts view or comment view, it sometimes upvotes and sometimes goes back.
I feel the edge is usually for going back and the comment/post can be swiped from any where isnt it?
This, my Pixel works fine, since the back gesture is system wide and can be activated from either side. On iPhone though using the right hand to swipe back is pretty problematic with a case.
