Rated 5 out of 5 stars
I do not know for how many years I have been a loyal user of Thunderbird. Due to compatibility, I have to use MS windows. But I try to avoid as many parts of the Bill Gates group.
I admire all those who want to invest so much time to add add-ons to a standard product. And more important .... to maintain it over the years. I was shocked that the basic code of TB is being adjusted to a large extent. And that it even takes you months of work to keep SmartTemplate compatible. This add-on is a very valuable addition to TB for me.
If someone does something special for me, he or she usually doesn't ask for a reward. Nevertheless, I would like to give a small gift for that. I therefore have no problem with those 5 bucks. But what is Marky Mark's contribution to this add-on?
Mark helped me build the support site and does some of the user support (especially German support) - he is also the one who managed the Add-on before I joined the project in 2012, when he was desperately looking for a developer to maintain the code.
Code changes have been quite substantial this round (we were as shocked as you), that's why this version took 7 months to complete; expect more frequent version updates in the future - a 6 weeks turnaround is usual for my Add-ons.
I am already planning some important changes for August / September in case Stationery won't be updated (I reached out to the author for many months but he didn't react anymore - maybe he walked away because of lack of time) - one of the problems with the expectation of "a working product" is that people do not know how much work is involved to keep it up to date.
