Figma file built-in .png layer generator for thumbnail previews

I personally, after a 15 year career, and my team have a vast library of design assets of many different file types. I have used both ACDsee and Adobe Bridge to organize those assets, but Figma files are always a black hole.

I would like to see the Figma file format (.fig) to have an automated, generated .png layer so that the software apps typically used to organize design files (like Adobe Bridge, ACDsee, XnView, Windows Explorer, etc) are able to display thumbnail previews of the Figma file.
