This is one of the best thunderbird addons I came accross! Its easy, intuitive and fast. It just works and never ever gave me any trouble. A very fine job!
There is one suggestion that I have though. Sometimes I need to copy (or move) large amounts of local mail to an imap folder. This often fails during the process because the copy function of thunderbird just isnt awesome. At that stage, some of the mails i selected have been copied, others havent and I have to start all over again because there is no way to tell which messages already made it to the server and which havent. The bad thing is that even when moving the messages, Thunderbird first copys all of them and then deletes the source, but only if the copy process was successfull.
Would there be any chance to modify removedupes, so that it can display dupes OR siglets. This would enable one to select all the messages that havent been copied/ duplicated yet. this would make removedupes also the only sync plugin for thunderbird and help out so many people struggeling with this poor TB copy function.This would be something that I am looking for for years and years!
