Split Singleton class into specialised server classes

[GTcreyon]

Describe the feature you'd like
Divide the monolithic Singleton into specific server classes that serve an individual function, to improve the organization of the project.

Do you intend to contribute this yourself? If so, how do you plan on doing it?
Maybe soon. It should be fairly simple to move the functions into other singletons, since they are not inter-dependent. If anyone else is interested though, go ahead.
