Feature

- What is the current behavior?

When I go offline, Netlify CMS goes offline too 😞

- What is the expected behavior?

It would be great to make Netlify CMS a Progressive Web App, allowing for offline functionality. This means that the user could create content without an internet connection, without fearing of losing it.

A PWA would also greatly increase the market share of Netlify CMS, as people could start using it on mobile devices, as in devices connected to mobile data network (although do see #441 Make the CMS work for mobile).
