The buttons are a tad small on mobile, like everyone mentioned. Next update will bring the dark theme and higher PPP options, I hope. Overall it looks much nicer than previously, much easier to read text and navigate the forums. Thank you for changing the font in the post/reply box.
I like almost all the changes, but I loved the ability to toggle between read and unread watched threads before. I mostly used the "unread" version and now I can't find that at all.
