Collector's Note Without Nostalgy I would not be able to keep up with email on a day to day base. it allows me to quickly sort those emails my filters have let through using the keyboard and archive them. In my opinion this add-on should be part of the Thunderbird core!
Ability to see attachment sizes ...
Collector's Note Attachment Sizes does exactly what it says: it shows you the attachment size! Should be part of the Thunderbird core in my opinion.
