I, too, hate the new UI changes, but here's another problem that I haven't seen many people talk about:
The space between two separate posts from the same user has been changed back to being greater than the space between two lines in the same post again, as indicated in this pic.
You actually fixed this a few updates ago and now for some reason you broke it again. Why why WHY?
(And no, the new "space between message groups" setting does not change this.)
Seriously guys... I like your app, I use it daily, but if this terrible update has not been fixed or rolled-back by the end of the week, both me and my wife will be canceling our nitro subscriptions. I am not paying for this garbage.
