Review for Nostalgy by GZzz
Rated 5 out of 5 stars
After using the dreadful move functionality to archive emails by clicking and some memorizing functions. This is absolutely the best add-on I have installed in Thunderbird.
It saves me tons of time. This add-on is a no-brainer and it is too low ranked with downloads. If some marketing is done it would help but this deserves to be in the top 10 of email utilities.
