Rated 4 out of 5 stars

I'm a Mac user (no Intel machine yet!), and tried to use the previous version on my Mac, but it never installed correctly. However, the new version (1.4.4) works great! I access my list from the "Options" pull-down (though it is only available when I have a "compose message" window open). I can now switch between five different signature blocks (one is even in UTF-8 Chinese) effortlessly. Wonderful functionality!!!

This review is for a previous version of the add-on (1.4.4).
