The idea 1795 asks for removing the overview page: https://connections-ideas.hcltechsw.com/ideas/IDEACNCTNS-I-1795
this is implemented in some way with HCL Connections 7, so when the highlights' page is defined as start page for a community, the Overview link is hidden.
When you now add a Rich Content Widget to highlights (a second one), then you get the message:
Cannot find Rich Content Instances. Please add one in Community overview
I had to open a case to get the information, that I have to switch the start page, then I get the overview back to add the rich content widget.
Do you really think that's the way a user should work? Please add the rich content widget automatically when a user creates the highlights' widget. We can't ask users to change to Community Actions > Edit Community > Switch to Overview > Save and Close > Go to overview > Add RT > Community Actions > Edit Community > switch back to Highlights > Save and Close
BTW if you add the rich content widget with Community Actions > Add Apps when you are in an app other than the overview, the widget is not found by Highlights!
