This may be something to look into at some point, the Drafts folder sometimes seems to have the drafts all over the place. EG if I have 4 drafts when I go in they are not orderly one under the other, sometimes side by side.
Secondly for some reason when I go to compose a new email at the bottom of my new email/draft other drafts will be underneath the new email. This can be disconcerting as I then hope the email won’t go to the wrong person…
