That's all fine, but when will the Dashboard get decent loading times? I know you're supposed to be a cool kid & email your blog entries, but I don't like what that does with line breaks.
Maybe they'll do something like they've done with the Archive view (e.g., http://staff.tumblr.com/archive) or the Mega-Editor (e.g., http://www.tumblr.com/mega-editor if you have Tumblr log).
