I just upgraded to version 2.7 of WordPress and I must say, I'm pretty impressed. This is a completely new design, which is surprising, since the last "new" design was done only a few versions ago. These changes, however, are very welcome. So far I'm digging the new interface.
I'm actually writing this post from the "QuickPress" section of the "Dashboard". I'll have to play around with it a little more, but for right now, I'm liking what I see.
