I am really looking forward to DO12.
At the moment the copy dialog shows the bytes that have been copied for one file (e.g. 10 MB / 120 MB) and the number of files that have been copied (e.g. 50 / 2000). Might it be possible to add a global byte counter (e.g. 530 MB / 23,413 MB)? The file count itself is sometimes useless as 50 / 2000 might mean 13 MB / 23,413 MB or 23,210 MB / 23,413 MB depending on the size and order of the files.
The windows copy dialog isn't that bad:
It shows the remaining file count and the remaining size. But lacks a progress bar for the current file.
I don't understand why the graph should be unitless (the windows dialog deals rather well with units and has a horizontal line that shows the current speed). Maybe it should even be a progress bar (maybe as an option).
