Obviously, it's a draft, therefore I've read it!
This is annoying as I use drafts to record a “follow up note” against an email received (but not replied to as there is no way of adding notes to emails in Gmail).
Anyone know how to stop it showing this?
Also odd is the fact that Drafts and Sent mail do not seem to conform to the labels model of Gmail.
I.e. there aren't really any folders as such, you are just seeing views of labels in the All mail folder.
