The plugin expose Module Manager functionality to blueprints so you can Load/Unload/Recompile module from Editor Widgets.

The plugin has a bunch of helper blueprint nodes to work on Blueprint Objects, like the possibility to add/remove Components, add/remove Interfaces and Compile them.

Examples can be found in EW_BlueprintNodes_UBlueprint.

AddComponent, RemoveComponent, GetInterfaces, ImplementInerface, AddInterface, RemoveInterface, CompileBlueprint, GetBlueprintFromAssetData, GetComponents, GetComponentsOfClass, GetComponentOfClass.

If you modify a Level Actors transformation in an Editor Widget the editor won't be notified about the change and wont prompt if you want to save the change when closing the map, so the plugin comes with the MarkActorAsDirty node that will fix that.

Examples can be found in EW_ToolbarButton_MoveSelectedToMouse and EW_ToolbarButton_RunConstructionScript.
