A great example of a few scholar-centric features would be:
The Publications app - once you add a publication to an OpenScholar website the publication can automatically be pushed to different repositories. Additionally, you can set bibliographic format styles display styles and use custom publications widgets to display certain types of content related to Publications.
The Classes app - helps faculty display and organize the classes that they have or do teach.
The Software app that allows individuals to promote the software they have developed, etc.
