When we're planning out a major campaign with multiple emails, it would be nice to be able to schedule the "Resend to Unopens" at the same time we schedule each broadcast.
In other EMS we can do this by duplicating the broadcast, creating a segment based on user activity (ie. "Did not open [email name]" and schedule it.
Otherwise, I have to put it on my calendar/task list to login to ConvertKit a day or two after I know a broadcast is scheduled and manually resend to unopens.
