I did find my files jumbled up after the upgrade so I spent some time re-shuffling them. I only hope it won't happen every time we up-grade, becasue it would be quite a task to un-jumble them as time goes by and I remember less and less what content is under what title. If you see what I mean. Otherwise, I like the new look. Still getting used to it, though.
Thank you,
Marta
