I am getting used to the new layout now. I won't complain about the theme as I know it is in a transitionary period.
The best thing is that the upgrade went relatively smoothly without losing important data.
It would have been extremely irritating if everyone had to re-register or if everyone lost their post count.
These things are never easy so congrats to all the folk involved in the upgrade.
Good work. I am sure further tweaks will win more favour. It is only a matter of time.
