One of the most useful plugins in Thunderbird. Quickly add notes like tasks or additional information to mails (like things agreed per phone call with the sender). Helps to boost productivity greatly.

Unfortunately, as of 30th November 2018, not compatible with Thunderbird 60.3., so all my notes are inaccessible.
Please keep up the good work and make it compatible to the newest version! Thank you.
