Import > Sub-Scene is confusingly named
Created by: akien-mga
The "sub-scene" term is used in several places but can be quite confusing to newcomers und especially developers new to Godot's scene system, see e.g. this Facebook post: https://www.facebook.com/groups/godotengine/permalink/703042476499016/
The PR #2928 based on @fiona's proposal already moves the "Export -> Sub-Scene" menu entry to an icon in the scene tree panel ("Create new scene from node(s)"), but the "Import -> Sub-Scene" entry could also use some love.
As this import function actually seems to copy the selected nodes of a scene to the current scene, a name like "Import nodes from scene" would be more explicit.
