Finally the missing add-on. It works exactly how explained in "Steps to Use the Extension" that pop ups after the installation.

This add-on doesn't actually copy folders, it just moves/copies the emails that are in them to another folder.

Hi, it will copy all emails in selected folder and all subfolders with messages as well. The top folder where you paste the messages must already be created in destination, or you can paste it in one level above.
