Folder view \ Mark as played \ Visual indicator

[DigitalRebel 0]

While using the folder view:

There is an option to mark items as played:

Which results in the items in that folder to each be marked as played:

Is there any way (or feature enhancement) where we could mark the original folder with a similar green check-mark to indicate when all of the items inside have been played?

Hi, the challenge is that this is all computed on the fly, so that's why we generally try to stay away from indicators on folders, because everything underneath has to be examined in order to determine the display.
