QlikView provides this capability so .....
Add a simple Hidden Y/N control icon ( similar to the Data Manager generated lock icon ) that allows the Sense app designer to password protect / hide parts of their script.
Useful not only for people wanting to offer commercial Qlik Sense products, but for partners and even customers where for various reasons parts of the load script need to be hidden from prying eyes such as section access, etc.
I think this is just a UI change in the Script editor, and should have no impact on QIX ?
