Like the new forum appearance and some new tools in post editor, at least I don't remember the Tables toolbar.
Encountered couple issues so far.
Searches I did in the previous design no longer work. I will have to do some organizing of subscribed threads.
I can no longer set threads I posted to as Solved or Unsolved. I assume this is now available only to the OP. Wait, I don't even see that option under Thread Tools for this thread.
