How long has 60+ been out? Don't you hate it when devs just plain IGNORE users and aren't even polite enough to say "I'm aware of it and an update will happen in the near future" or some such thing? My god. And someone is questioning why people are posting one star reviews. Well yes, it does NOT work any more. This is really more an issue with the devs of Thunderbird that we even have to use an app like this to "make things right" in Thunderbird. Tbird team needs to get their head together and make it possible to actually SEE the subject lines of mails in the list or make it possible to change the size in the program without using a third party app. Holy cow, it's just deplorable you can ignore such a basic function.
