It would be great if when doing operations that take a long time, that the time remaining be shown as The full date and time when the operation will be complete.
For example, when copying many large files, instead of the estimate being 3 days 14 hours and 46 minutes, it would say Monday 5/22 at 2:06 pm.
I always wind up doing the calculation in my head or trying to do it in Excel. This would make it much simpler. I hope you will consider this.
