Smart Folders - Hide Documents/Views

I am wondering if a configuration item can be added to Smart Folders to toggle/filter showing attached documents and embedded views. I think it is really valuable in some cases to be able to view embedded/contextual views and documents in the smart folders. However, in some cases, this can actually create a lot of confusion and be very messy (in particular in multi-level hierarchies):

Being able to turn them all on and off would be great. Having the ability to actually filter views and documents shown using fibery’s powerful filtering (e.g. filtering views by type or name and documents by name) would be the cherry on top :cupcake:
