In the SharePoint App, the Find page shows frequent sites and people, which is super useful for quickly getting to sites or people your often interact with. The same Frequent sites functionality can be used in other places in SharePoint with the Sites web part.
It would be great if there was also a Popular Sites section, and even a Popular People section (though that name might need some workshopping!). This would make it easier for users to find important sites quickly, even if they don’t access them often. It would be especially useful for new users.
With this addition, the existing sections may need to be renamed to be clearer, e.g. Frequent Sites would become My Frequent Sites.
