It would be nice if the download progress bar at the bottom left the display would use the download times if entered. Instead of the bar continually going from left to right until the image download is complete, it would instead move at a rate that puts it at the right side after the entered download time or the download actually finishes.
So when the bar is half way between the left and right, the download would be half done.
This would make it a true progress bar, rather than a horizontal spinning wheel-like element.
It would be really cool if it would also display the percent complete. It might need to wait until after the first picture at the given bin and subframe size in order to determine the size of the image.
