Subsystem Browser Plugin for Unreal Engine

Subsystems provide an easy way to extend engine functionality and implement new features while avoiding the complexity of overriding engine classes or packing multiple independent features into a single class. Check Programming Subsystems article if you haven't tried them yet.

With Subsystems being a great tool, Unreal Engine Editor does not have a default method to visualize them or allow changing their properties at runtime.

Plugin provides a dedicated Subsystem Browser panel to display active subsystems with property editor.

New Subsystem Settings panel provides an easy way to interact with config properties within Subsystem-derived classes without need to create a standalone UDeveloperSettings class.
