List OpenType features on the typeface information page.
OpenType features are referenced in the 'Details' section with a link to a generic information page, but which features are actually supported by the current typeface are not listed.
Currently, seemingly the only way to see this information is to add the typeface to a web project, edit the project, and look at the highlighted options under the 'Character Set' heading.
This is important information in certain situations, as the presence of certain OpenType features may influence whether the typeface is suitable or not (e.g. finding a font with tabular figure support for a data-heavy application).
