Rated 4 out of 5 stars

Excellent job, request accomplished. Right click on folder is done. Same would be very practical to be valid if a specific email in a folder is selected and we have to move it to another folder. TB default is a little cumbersome and time consuming.

This review is for a previous version of the add-on (1.2.0). 

Nope, I won't support moving a single message. This extension is meant to move all the messages of a folder (and optionally of its sub-folders).

Right click menu on an email contained in a folder (inbox, sent, Local folders etc.) is missing. Addon should recognize automatically the folder in which the emails are kept and user should define only the destination folder.

This review is for a previous version of the add-on (1.1.2). 

I just published version 1.2.0: you can now select the source folder by right-clicking on a folder in the folders pane.
