One quick thought and a feature request.
Using the dark theme, the icon indicating a thread is being watch watched and the icon showing that a thread contains a poll both use a purple color. If the watched thread icon was changed to orange, it would be much easier to notice at a glance. Or change poll color to orange. Either way would work.
I'd also still really like for thread creators to be able to change their thread titles.
It's hard to tell if new posts in a thread mean new news, or people talking about the same news. As another example, if someone makes an official topic for Anthem, I'd rather they not have to make an entire new thread for a simple "double XP" event they're doing over the weekend or whatever. And if they do make a new thread, there's also a good chance that people will start posting in that thread instead of the OT.
The new design looks great, though. I already appreciate the bookmarking feature, and I look forward to hearing about any other features that I might have overlooked.
