A time that it will finish is a great idea!
Bambu needs to think of a print like using Google Maps to drive somewhere. You want to know how many minutes left in the trip, and the estimated time of arrival is also a great idea. Those stats need to be BIG. And using the right hand of the screen to show them nice and prominently makes a lot of sense instead of an image of the printer.
Percent is a useless statistic to me, it could mean anything. It doesn’t help me at all know how much time I have to goof off before I need to be back to start the next print.
