Thanks, if that was a (generic) reply to my comment.Other browsers embraced the file system api long ago, precisely because of being crucial for pwas.Another good idea would be to have something like rfs (vfs on the real file system). 99% of the work...
If nobody mentioned it, do please provide means for data to become truly persistent, maybe asking the user to acknowledge if needed. Current vfs implementation is just hopeless for any serious pwa application. Thanks
