Hello,
Nostalgy is a verry useful addon for Thunderbird.
But sometime, it is verry slow. It can take one minute or more to move a message from a folder to an other.
Did anyboby already experienced that ? Have you any explanation for that ?
Many thanks in advance

This review is for a previous version of the add-on (0.2.20).
