how can I mark sent emails to remind me when they are not answered?
I'd like to be able to mark/flag/tag outgoing emails to which I expect a reply so that I am reminded within X hours/days if they have not been answered. I could, of course, move sent emails to a "pending reply" folder but it would be nice to automate that action or have some app pop up to ask if I want a reply to enter the deadline for expecting it. That way I get reminded if a message isn't answered in a timely manner. Thanks.
