Collector's Note Essential Thunderbird Plugin. You simply can't do without this.
Enter accents, diacritics, diaeresis, umlauts, ligatures etc. with keyboards of various countries (us,uk,ie,fr,it,ru,de,sv) - via easy to remember shortcuts or menu. Also supports all textboxes of the application (such as search, filters).
Collector's Note For all multi-linguists who have to use a non-native keyboard! Totally cool; just use the shortcut key and you can tÿpë Ümlãuts, diacritics etc without having to remember lengthy ASCII codes.
Allows to place a copy of sent messages (aka FCC) into the currently active folder or any other folder you choose, when you create the message. Usually the copies are placed into the 'Sent' folder. For replies, you may also move the original message.
Collector's Note If you (like me) still rely on Folders to keep your zillions of mails organized, this one might be quite a productivity enhancement - you can answer to an email, and instead of filing your reply into the Sent folder the copy can go to any other folder, (Usually the one you are in) - so you can see & treat your message thread in-line, which results in less searching and moving. Phew, I hope I explained that one right ;)
