I'm fairly comfortable with a loading bar that tells me "15/75 things done, working...".<br><br>A time estimate on top of that is nice, but I don't care if it's precise, I just want a ballpark. I care way less about the difference between 15 and 16 minutes vs the difference between 10 minutes and an hour. Is this a "go to the bathroom" wait or a "go have supper" wait, or what? Just a very rough estimate is good enough.
