Plus: the new reply icon is a big improvement over the envelope. It looks like a public discussion now.
Minor bug in the highlighting of new comments, though: clicking on any link to a comment (e..g in the recent comments or your inbox) causes you to go to a partial view of the containing post, and it resets the "new" status for the page, meaning you can't then look around for other new comments on that page. The newness should only be reset when you view the page proper, if it can't be reset on a comment-by-comment basis (and I'm assuming it can't.)
(I still think the "parent" and "permalink" icons need improvement, but I don't have any concrete suggestions. Also, it appears that redacted comments show unredacted if they've already been sent to your inbox.)
I saw some discussion posts earlier talking about a LessWrong redesign, and now that things look different, I guess that it's been implemented. I'm always slightly annoyed for a while when a site I use gets redesigned because I have to relearn where everything is, but it eventually wears off once I'm used to the changes.
My initial impressions:
"Hmmm... it seems like the category menus have been replaced by dropdown menus. It's not like I used many of them anyway."
"Okay, I've clicked my name to see my recently posted comments. Now, where's the link to see it in context? Oh, I guess I have to click that icon in the lower right corner. For some reason I was looking for something at the upper right of the comment box."
"Well, that worked. Now how do I click to the parent comment? Oh, wait, it's probably one of those new icons in the lower right corner. I'll just mouseover them to see what they do..."
::realization sets in::
"AAUGH! LESSWRONG IS USING MYSTERY MEAT NAVIGATION!!!"
So, what does everyone else think of the new redesign?
