Mark All Read:WE
Mark all read (Web extension) - Adds a toolbar button to mark all unread messages in current folder as read.
*Note*
This addon works much better in newer versions of Thunderbird (v91). Thunderbird's WebAPI's were very patchy in older versions.
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.
