I do want to say that I found somewhat of a workaround that kind-of answers this coding request.
(I did get a nice email from the Xentient folks and they said they'd consider the feature in the future.)
Here's how it goes:
Switch the explore view to Details and sort by Date Modified Descending. (This is what I always used to use) and then if you use View-Arrange Icons by (Date modified should already be selected) and then Pick "Show in Groups" it works rather nicely. It shows the files modified "today", "yesterday", "last week" etc in descending order by "details" view. Which is rather nice!
So in the end, I need to thank good ol' Microsoft for thinking of this! C'mon, you have to admit they do build fairly good software sometimes!
