In Google Chrome's Developer Tools' Sources tabs there is a left side panel which has three tabs with the first one being Sources. Is there a way to download a folder with multiple files and nested folders from this interface? You can right click individual files and 'Save as...' but this is cumbersome.
Currently not possible.
"Saving whole folders is not currently supported."

It's not possible to do directly with Chrome, so I made a batching extension to automatically fetch resources to the Downloads folder. You can have a try.
Just do right click -> save as html -> in type select (complete webpage).
Works on OSX.
