The pop-up that previews the first post when you hover over a thread... would be more useful if it revealed the text of the first unread message instead of always the first message.
I can't agree. The idea of the preview is to tell you what the thread is about, but the "first unread" post would only tell you what that post is about which might have little bearing on what came before or after.
The issue I have with the preview is that its slower (not a fan of the gradual "fade-in" way it appears) and much bigger and more obstructive than it was previously. It blocks several other thread titles when it (slowly) appears and I don't remember it being that way before. I recall the preview box being wider and therefore needing fewer lines of text which made it functionally smoother in appearance.
