Reader-friendly typography that adapts well to mobile devices.
Flexible figure layout options (e.g. displaying figures at a larger width than the article text).
Tools for making articles easily citeable, as well as for generating Google Scholar compatible citation metadata.
The ability to incorporate JavaScript and D3-based interactive visualizations.
