On many occasions I have checked my email in MW with a small number of emails showing and then downloaded them into my email client Thunderbird (TB) but noticed that one or emails has managed to slip in during the small time between checking the mail in MW and downloading in TB. For example, MW may be showing 3 emails but I actually download 4. That's fine when there is a very small number but I am on several mailing lists and often have a large list (more than 30) in MW. Emails can then turn up in TB that I have not noticed in MW due to them slipping in at the last moment. Whilst there's nothing that can be done to fix that occurence, it would be nice for MW to show the quantity of emails it currently has in its list so that, if I see TB announcing that it has downloaded a different quantity, I can find them straight away and not discover them hours, days or weeks later (I filter all incoming emails in TB but often leave them unread as I tend to read them in the MW preview pane).
Hope my rambling on makes sense!
