Modern Search with Hub sites
I'm currently working with a Global fortune 500 organization on migrating from SharePoint 2010 to SharePoint Online. They are fully embracing the modern experiences, however we're finding certain aspects of the new experiences are confusing to end users, and a significant amount of change management is required to help them understand how it's functioning.
SUGGESTION: The modern search experience's default text in the box is "Search Across Sites". What this is doing is actually searching across the sites configured in the current hub. What would be FAR more intuitive for end users is if the default text leveraged the name of the hub, so if the hub's title was "Human Resources", the search box should say "Search across Human Resources".
