Review for MinimizeToTray Reanimated by otzmotzfitzifotz
Rated 5 out of 5 stars
PLEASE make it work with the new Thunderbird 68!
I'de be happy to donate if you provide something like a paypal link. Couldn't find anything like this on the github page.
Hope the Thunderbird developers will include this feature natively. This is a must-have for any Email client.
