Rated 5 out of 5 stars

I was so pleased to read that you're working to make this work in Thunderbird 60.0. To me (and many others), Thunderbird is ugly without your plugin. i just (almost) updated to 60.0 and it was so ugly, I'm staying with 52 while waiting/hoping for your new version. Thank you for doing this.
