WP auto-saves entries now…
I am completely digging the new WP 2.2! I don’t know how it works but I noticed on my other blog that it was auto-saving my entry as I was writing it. Granted, it’s not every second or anything but it is enough where if you’re writing a rather long post, you aren’t going to lose anything significant.
I can appreciate that even though I’ve never had a problem with my posts disappearing on me. But my friend Rachel is what I call an all day writer. She’ll work all day on one post. Just off and on but still. 
Had to share, I just love the feature. 
Random side note: They stuck the preview into a link instead of it loading at the bottom of the writing post page. I love that, too!
