Complex classes like Settings often do a lot of different things. To break such a class down, we need to identify a cohesive component within that class. A common approach to find such a component is to look for fields/methods that share the same prefixes, or suffixes. You can also have a look at the cohesion graph to spot any un-connected, or weakly-connected components.
Once you have determined the fields that belong together, you can apply the Extract Class refactoring. If the component makes sense as a sub-class, Extract Subclass is also a candidate, and is often faster.
While breaking up the class, it is a good idea to analyze how other classes use Settings, and based on these observations, apply Extract Interface, too.

This check looks for access to properties that are not accessible from the current context.
If you need to make a property accessible to another context you can either raise its visibility level or provide an accessible getter in the defining class.
