Very Cool! Rated 5 out of 5 stars
This extension is great. Nice going.
I haven't fully kicked the tires on it yet but it took just seconds to figure out how it works and I like it.
I'd love to be able to use it in Thunderbird 3 (when officially released) so I hope that you keep that in mind.
New version supporting Thunderbird 3
Thank you for your comments. Just uploaded a new version 1.1.0 that includes support for Thunderbird 3 (3.0b2 as of May 2009). It comes with some new functionality. Hope you find it useful. I welcome your comments and feedback.
