I want to be able to delay e-mail that's in my inbox. I would use this for
e-mails that I need to deal with later. So I'll click the delay-1-hour button
and after 1 hour the e-mail's "New" flag gets set again. That's much more
efficient than marking it red which is what I do now, because I will be forced
to read the e-mail again when it becomes new again.
