Rated 5 out of 5 stars
I couldn't edit my above review, so here's the update: the author & I exchanged a couple of emails (he got with me very promptly), and it works beautifully now. This is an incredibly handy Extension, and saves me LOTS of time scrolling to & fro to file my mails. Just exactly what I was looking for! Big THANKS to Paulo for saving me frustration with my OCD!This review is for a previous version of the add-on (0.2.4).
