When initially shipping the File System Access API we shipped a bare minimum API surface for showing file and directory pickers. We're now proposing adding a couple of frequently requested (and commonly supported in other file picker APIs) options to let websites provide a couple more opportunities to influence the behavior of the file and directory pickers. In particular we want to let websites give suggestions for the name and location of files and directories that are being saved or loaded.

Motivation

This will let websites provide more user friendly user experiences when interacting with the File System Access API.
