I sometimes miss unread emails because they are sitting in sub folders
Let's say I have a folder called Trips with 3 sub folders called, Florida, Boston, Washington respectively.
If Florida has one unread mail and Boston has two unread mails, I would like Trips to show
3 unread. By default it seems like it shows
0 because there are no unread mails in the actual Trips folders (not counting sub folders).
Is there any way to change this behavior?
