Nice add-on.

But all attachment is not shown if lot of attachment is there.

If Add a print button is there, it will be nice.

This review is for a previous version of the add-on (0.2.1.0). 

well you could actually scroll through all attachments, but yes, this is not the way it should be. i am working on it!

and about printing, it should be possible to print the mail via the "other activities" button on bottom left of the mail header. And ctrl + p should also start the printing dialog. But i might also add a print button to the menu bar in a later release.

thank's a lot for testing and giving feedback! :)
