Manually sort folders 2.3.0
by Jonathan Protzenko, Itagaki Fumihiko
This extension allows you to manually sort (order) your folders in the folder pane of Thunderbird or automatically sort them, but in a better way. This extension also allows you to re-order accounts in the folder pane.
About this Add-on
By default Thunderbird sorts the folders of an account alphabetically. This extension allows you to choose a specific sort order for your folders, allowing you to put the most important ones on top, and manually order them.
This also works for newsgroups inside a news accounts, and also works for sub-folders, and sub-subfolders, etc.
As a bonus feature, you can also re-order accounts as well, there's an extra tab for that now. The latest version now also allows you to choose the default startup folder.
