Folder Comparisons : Progress based on size with ETA for lengthy tasks

[meteorquake]

I'm running a large binary compare (probably about 1Tb), and the progress duly shows 'Items Total' and 'Items Compared'.
It's already scanned the files ahead and knows what total size to expect just as it knows Items Total.

• Because it's a large compare it would be useful to have an ETA based on target size remaining and contemporary byte rate. It's not really so predictable from the item count because different folders have different types of item. Having an ETA would give a useful sense of the timescale of the operation.
• Also useful would be Bytes Compared and Bytes Total (with commas, or normalised format such as Kb or Mb or Gb) to go with the Items Compared.
• Also useful a summary of differences so far (x Same, x Different, x Left, x Middle, x Right)
• Perhaps these only need to kick in showing when it's looking to be a lengthy process.
