Direct writes to local disk images

I was looking around the settings in google chrome and I saw there was a `File Editing` option in the site settings
`chrome://settings/content/siteDetails?site=http%3A%2F%2Fcopy.sh`

Could we use this to read/write directly to the disk file so we don't have to press `get hard disk image` every time we want to save?

It would be a big change but I think it would speed up the emulator a lot and it would use a lot less memory.
