<brief_description>
Godot editor's control for selecting [Resource] type properties.
</brief_description>
<description>
This is a [Control] node similar to the one used in the Inspector dock when editing [Resource]s. It provides options for creating, loading, saving and converting resources.
[b]Note:[/b] It does not include an editor for the resource.
