Sounds like a neat add-on.

I couldn't install this add-on. Normally I install .xpi files to Thunderbird but this one is .xml. When I try to install it Thunderbird says it is an invalid package. I tried to local the author for support through the various pages (in Greek?) but I couldn't find an email address or contact link.
