and there appears to be no way to submit the form without clicking the button. Part of the joy of the previous flow was I had the bookmarklet bound to a shortcut, when it opened it auto-focussed on the tags box (with URL and title pre-populated), autocompleted my tags, and enter would submit. I could be done and on my way without even thinking in around 1-2 secs. This is about an order of magnitude slower and as you mentioned prone to tagging error.
