Inappropriate file-contents

I've been trying to install this app from the extension manager some times ago and discovered recently that some of the attachments (in particular to MailArchive.Loading and MailArchiveCode) contain attachments of XML files with a load of somewhat personal information that should not be there.

I've noticed this for the file TimeLineFeed-MailArchiver.xml and potentially for some documentation screenshots.

I don't know enough of the app to know if this is critical for it to function but it is rather inappropriate to deliver this amount of personal info with applications.
