Just works great in win8.1 with thunderbird 31.5.

Options on right click to restore only the window you want would have been perfect.

This review is for a previous version of the add-on (0.5.4.1-signed).

Hi, thanks for the nice review.
Hidden windows are already listed by name in the popup menu, when you right-click on the icon.
