Rated 5 out of 5 stars

Small feature request:
The print action should be extended to include an option to whether to print the message or the attachments. Maybe rather a separate "Print attachments if named..." action could be introduced with a regular expression field that would match on the filename of the attachment that should be printed.
Otherwise a really good extension what I tried worked as should.

This review is for a previous version of the add-on (1.3.2).
