Powerful Contextual Features Like file previews etc

I use an excellent PrefPane called FolderGlance (used to for years), it allows you to add contextual menu items AND to preview files handled by QuickLook still in contextual browsing mode (a sort of FinderPop on steroids)… If this type of thing could be integrated in TF… I can always dream… In any case FolderGlance I not updated much, but it still works in Yosemite.
