Automate Adding Bookmarks to

I use to store all of my infrequently used bookmarks, but I've found that browsing by tag just isn't very efficient for me. I always use a full text search through my bookmarks to find what I'm looking for, so what I'm really looking for is a single-click save solution similar to the star button on the Flock browser.

Greasemonkey comes to the rescue with the autotag user script, but the problem is that you can't edit the bookmarks by clicking on the tag button, because that script always immediately submits the form, and also duplicates the tags.
