Nostalgy for ThunderBird 0.2.17

Nostalgy is an extension for Mozilla Thunderbird whose purpose is to save time by doing more operations with the keyboard. If you want to use Thunderbird without sacrificing the productivity you had with good old mutt/pine, this extension is for you!
Nostalgy adds keyboard shortcuts to change the current folder, to move/copy selected messages into another folder, to add/remove/view tags; the selection of the target folder is made through an auto-completion box where you can type part of the folder name.
Nostalgy for ThunderBird adds some commands to improve the navigation between Thunderbirds three panes.
