Adding pictures to the folder icon on images folders

I really like the way Zorin has customized the gnome shell. But there is on feature that it is available on windows and on KDE. That is showing over the folder icon several pictures that contain that folder.
There is a plug-in that is called Cover thumbernailer but It does not work properly at it has been a long time since it was updated.
I can install Dolphin, but nautilus is better integrated on the system. Please consider adding this feature on future updates.
