this is my main complaint with 2.5 ….. this was a few steps in the wrong direction……….a plugin to fix this is BOUND to pop up soon….
There is a WordPress Hack which is simple to implement for this issue made by Judy at persistentillusions.com 04/16/08 archive to make your Write post/page screen look pre-2.5 at

Basically it involves upload a few php files and a css file to wp-admin folder plus refreshing the page. I logged out and after log in, viola! the write screen I love was back to mama 🙂 I just couldn’t bear using WordPress as a CMS and scrolling down a frame with 6 entries at a time to select from 60+ categories. I hope this helps you till a wordpress plugin comes along.
P.S. You might like to vote for and comment on this Idea: “Revert 2.5 Write Screen to 2.3” at http://wordpress.org/extend/ideas/topic.php?id=1354. Hopefully, this will be incorporated by in the next version. Cheers.
