This is a great addon which used to be very useful. Unfortunately, as @SantiagoSantee has found, this addon no longer works for me since the TB 52 update.
I've tried disabling all other plugins, and re-installing this plugin, however that makes no difference. The addon looks ok and can be configured, however does not auto change the sender when the recipient changes. I'm using Linux (Fedora 25).
