What's the difference between case properties at the menu level and form level

Hi, at the menu level, there are case list and case detail, as below

And in the form level, if I click the gear next to the form name, under the "Case Management" tab, there is "Save Questions to Case Properties", as below

What are the differences between these two?

Hi,

The Menu List and Detail screens configure the Read-Only view of collected data, while the Case Management Tab saves properties collected from the form into that database.

To learn more, the Case Management Module of the CommCare Fundamentals guide is a good starting point.
