Good job. Add-on version 2.2 is now fine.
It would be nice to be able to put your own "I would like to open this file anyhow" for a different language version.

This review is for a previous version of the add-on (2.2). 

Thank you for your review. With the new version, translating the Add-on got much easier and can be done with an arbitrary plain text editor like the notepad.

The translations are located here:
https://github.com/jdede/WarnAttachment/tree/master/warnattachment%40jdede.de/_locales and are currently available for German, English, French and Italian.

I would be happy if you could provide the translations for your language as a messages.json-file either via mail or as a pull request on github.

Thanks and best regards

A very good add-on.
In version 2.1 there's a bug related to opening files with the EML extension. It allows you to open it once, but then there're problems opening any files whose extensions aren't defined in the options.

This review is for a previous version of the add-on (2.1). 

Dear MX_EH,
thank you for your feedback.
I have just uploaded version 2.2 which fixes this bug. The new version will be updated automatically within the next days.
