I use WordPress mainly as a CMS. Many sites have 30 or more pages and not a single post. I know that this is not normal and perhaps wasn't what WordPress had in mind when they created it. But I think that WP as a CMS Rocks!
I noticed that after the upgrade, when you update a page, you no longer have the message:
Page Updated Go back(link)
Page Updated View page (link)
I can see why you did this, but in fact, this makes WP less useful as a CMS because now I have to click the edit page to edit my next page and need to do a few more clicks if my page is on page 2 or 3, etc...
It's not a big deal, but the go back link was better.
