Review Form/Email Attachments
I frequently run into reviewers who have indicated on the review form that their comments are attached, but no files have been uploaded. Similarly, there are many instances in which I alter email templates to mention an attached file but forget to include it, requiring a follow-up email. It would be helpful and likely save time if reviewers and managing editors could receive a warning pop-up before submitting a review/sending an email if they have mentioned an attachment but not supplied one--the Rackspace email application currently offers this feature, and it has proved useful countless times.
