I want to know whether guests checking in the upcoming week have opened my 2 critical emails or not. Right now that's a pain to figure out for even just my 4 properties. Adding a check-in time (after & before) filter in the communications history would solve this problem and limit the display to just those bookings coming up, rather than the way it shows it now which is all bookings. It would also be helpful if the booking check-in date was displayed and the list could be sorted on it.
