Feature Request: Synctoy Shell Extension

The concept of five predifined actions is very convincing. The need to setup
folder pairs seems cumbersome in many cases. In my mind, an
Explorer-Shell-Extensions that adds the five actions to the right-click+drag
menu, with the dragged drive/folder being the source and the drive/folder
dragged onto being the target folder would be very convenient. I would also
prefer for the folder-pairs to be stored in the application-data foler
instead of my documents.
