This feature request is for those of us who need to pull out a calculator to know how many hours and minutes are in an estimated time display of 464 minutes.
Please add the three lines of code necessary to display this in human readable form i.e., 7 hrs 44 minutes. With less than sixty minutes remaining it should show as minutes only. More than 60 minutes, it should show hours and minutes.
I don't think there's any reason to put this in as a Tools/Options setting but just in case there are people who natively understand and prefer to see something like 464 minutes, you could put this in as an option selectable by the user. In that case allow users to select between HH:MM and MM time remaining display.
Extending this argument a bit further perhaps it might be useful to have DD:HH:MM (Days / Hours / Minutes) for really long prints.
