What can users do with the JSON editor regarding configuration files?

The JSON editor allows users to overwrite current configurations, which means they can make changes directly to the configuration files that are in use. This functionality is critical for users who need to customize settings or adapt the infrastructure for specific needs, ensuring that the configuration applies immediately after modification. By enabling direct overwriting, the JSON editor facilitates a seamless management experience, allowing for efficient updates without needing to create entirely new configuration files or manually replace settings.

In contrast, the other options do not fully encapsulate the capabilities of the JSON editor. For instance, while users may view configurations and share them, the primary and notable feature here is the ability to overwrite existing configurations, which enhances user control over the application's setup.
