[FEATURE] can we get _isInspectorOpened outside of the package?

[tegarnugroho]

The feature request is asking for the capability to access the _isInspectorOpened feature from outside its current package. At the moment, this feature is confined to internal use within the package. However, the requester is suggesting that allowing external access to _isInspectorOpened would enhance the flexibility and integration potential of the codebase. This change could be beneficial for tasks such as cross-feature coordination or for better monitoring and management across different parts of the project.
