Select absent directories while "compare"

There is a useful function: "Compare directories", but it compares only files. Is it possible to mark also absent subdirectories?

Thanks for your suggestion.
We will see, if more people ask for this.

@konstbel: Good idea! I also hope that WinSCP's 'Compare directories' feature can align identical files and directories. A better dark color mode would make the comparison more easily visible.

I have added this request to the tracker:
