archive-by-time
With the filter function comes with thunderbird, all emails met rules will be moved to a specific folder. As time passed the folder would grew bigger and I wanted to put all emails into sub folders classified by year.
Last selected message
The add-on remembers the last selected message in visited folders. After restarting Thunderbird, when we enter the previously visited folder, this message will be displayed, just like in Microsoft Outlook.
RemindMe
Moves email into Inbox/RemindMe folder, and moves it back into Inbox after chosen time.
Move Folder (context-menu)
Adds the "Move to" menu entry to the folders panel context menu, allowing to move a Local folder (and its content) to another.
This feature is similar to the native one within message(s) context menu ("Move To"), but it applies to the folder tree.
AutoMover

This Add-on installs a button on the mail toolbar that will when clicked select all messages within the folder.
To create your own collections, you must have a Mozilla Add-ons account.
