Review for Thunderbird Conversations by IUSR
Rated 5 out of 5 stars
Entirely overwhelmed by all the features! Can't believe why I missed this addon for so long.
Agree with others on that the first-time setup wizard could be a bit confusing, especially with all settings hidden by default, but on the other hand, even with them shown up front, users probably won't get the idea without a picture comparing the effects.
That said, I'm so far happy with the default settings and the changes to Thunderbird UI; they are not ideal if I were to customize them, but they seem to make the addon work better.
