I just upgraded this blog to WP 2.7. I’ve done about three other implementations of 2.7 before I got to this one. This was actually the first upgrade (the others were just straight installs). Everything with the upgrade went smoothly.
New Layout
I really like the new layout of the admin control panel. Having everything down the left side creates a lot more room for the editing pane. The dynamic layout also flows quite well when the browser window is resized. I immediately knew I had 4 comments in moderation that I needed to deal with, and it was easy to see. One of the only things I dislike is there is a big red 3 next to my plugins menu. I’m not sure what that’s all about, but it makes me feel incomplete. It’s like that error message you can’t get rid of…
EDIT: I figured out what the error messages for plugins were. I had 3 plugins that needed to be updated.
