A MonkeyLoader mod for Resonite adds a type picker into Component Selector / ProtoFlux Node Selector by utilizing Component Selector Additions.
Just drop any reference into the picker and choose the type you want.
First, make sure you've installed MonkeyLoader and the necessary GamePacks - combined releases can be found on the page of the Resonite GamePack here: https://github.com/ResoniteModdingGroup/MonkeyLoader.GamePacks.Resonite/releases/
You also need to install Component Selector Additions.
Then all you have to do is placing the provided TypePicker.nupkg into your Resonite/MonkeyLoader/Mods/ folder.
