Now this is cool. Blogger has apparently implemented an “auto-save” function for blog posts, meaning that if you’ve composed something at work and forgotten to save it as a draft or if your browser crashes in the middle of a composition, you can simply restore your post from the last auto-saved version.
Matt has indicated that he’s wanted to do something similar for WordPress for a while. I’d like to heartily endorse this notion. Maybe for WP 1.6?
