Exposing Settings Tab Values

I was wondering if there was a way to read the values for the configuration on the Settings Tab in code. Read-only access to things like Pixelblaze Name, Limit Brightness, CPU Speed might be helpful for an idea I have. Being able to read these values just as I am able to read the global called “pixelCount”
Also, being able to read the value of the main UI’s brightness slider would be great too!
