Display Autoloads in the inspector node selection window

[thornySoap]

Describe the project you are working on

A simple beginner Flappy Bird fake with an SettingsHandler-Singleton of type ResourceHandler autoloaded. I want to add a settings screen, for which I use a ResourceElement-UI element. ResourceElement has a variable of the type ResourceHandler exported.

Describe the problem or limitation you are having in your project

I want to assign the Autoload to the settings-ResourceElement. But for this simple thing I need to create an extra script for it which seems weird to me:

extends ResourceElement

func _ready() -> void:
    resource_handler = SettingsHandler

Describe the feature / enhancement and how it helps to overcome the problem or limitation

Since Autoloads are always "there" no matter if running the main or any other scene alone, they could be shown in the "Select a node" popout in the inspector:

__

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

The Autoloads could be shown above the root node.

If this enhancement will not be used often, can it be worked around with a few lines of script?

Yes

Is there a reason why this should be core and not an add-on in the asset library?

N/A
