Use case: in some situations, the developer, based on a requirement from the business, would need to make it so that the domain model entirely is locked from editing, when the app is opened in Studio/Studio Pro.
Proposed solution: add a feature to the Studio/Studio Pro that enables the domain model of an app, to be marked as ‘read only’ as the System modules are (https://community.mendix.com/link/questions/117941).
