Good work so far.
Two suggestions:
1) In a typical post, in the left column with the poster's name/avatar/details, can the inner border be eliminated, so that the darker part is stretched all the way in that rectangle? Seems like it would eliminate an extraneous line and make the page look less busy.
2) Going along with this, can the spaces between each post be eliminated? Seems useless too.
Otherwise, looking good so far, can't wait to try out some of the new features.
Edit: Ok, third suggestion. Can we switch the placing of the User CP icon and the search icon at the top, so that the gear is next to "home" ? I'm so used to clicking back and forth between the home and User CP to check front page threads versus subscribed ones.
I guess that leads to a fourth suggestion, which I imagine someone has mentioned, which would be more threads to see on the front page with recent posts. I think it's at 5 right now, which is a tad few.
