It would be very handy to see what time a copy will end as an option to hours/minutes remaining.. This way, if it's a long time from now you don't have to figure it out. I find myself doing this often during data migrations.
I mocked up what I consider an elegant solution that likely would be pretty straightforward to implement since all the info is right there already. It just needs a formula to add the time remaining to the current date/time.
I hope you will consider it. It Involves a little hyperlink that just toggles the display back and forth.
