Shima Dev Tool is a Chrome extension that offers a dynamic toolkit for securely modifying project configurations directly in the runtime environment. With this tool, users can customize roles, environments, dynamic configurations, and more with ease. There are no limitations on the types of configurations that can be created, providing a versatile solution for project management.

One notable feature of Shima Dev Tool is its focus on security. The tool operates with only one permission - storage, ensuring that all configurations are securely saved locally on the user's computer. This means no external servers or HTTP requests are involved, keeping sensitive data encrypted and private.
