More information is not a bad thing, even if you find it useless it may be useful for someone else, even is it's purely psychological. Knowing how much you will copy and how much have been done is not useless I think, especially when DOpus knows it and use it to calculate the progress bars.
And it's displayed for individual items of the queue, how the same info for the whole queue would become useless ?
And the size of the queues pending would also be a nice information to display, to know how much is still left to copy.
The "graph on copy dialog" was already a heated issue, and I remember how you were strongly against it, and now it's in DOpus 12.
Now, only this information (even optional) is missing. (Although, I'm not sure about displaying it in bytes, a smart unit is probably better, but that's almost obvious).
