add tutorial on how to use the level editor for beginners

[Anyone-Anonymous]

I had this idea a few days ago, which consists of adding a tutorial that appears when you open the level editor for the first time, teaching you how to use it. also see the tutorial again in the settings. the tutorial could include simple things like:
-how to add/delete tiles and objects
-how to save a level
-how to add tilemaps
to more average things like:
-how to edit tilemaps/objects
-how to add paths
-how to create different sectors
to more advanced things like:
-how to add bezier curve
-how to use script
-how to change sprites/tiles
this would be useful for beginning players who still don't know how to use the level editor properly, but it's just an idea.
