As @jekyllrb picked up, we've added a much improved mobile experience to Prose. In an effort to make this an authoring environment for more than just the Desktop, You can now create, edit, and manage files hosted on GitHub much more easily from a mobile device.
Other notable features include:
- A desktop layout that adjusts nicely for smaller screens
- Glyph icons which provide excellent scaling between interfaces
- Where we aren't using glyphs on some icons a retina optimized sprite sheet is served.
