Adding notes to folders or classes?

Hi,

I would like to store some notes in specific folders (readable within the editor), or display some notes when a specific class are dragged into the level/viewport. Is there anything available in that regards?

Hello! There is a blueprint description in the class settings, which it will look like this when you hover over it in the content browser:

as for notes when a class is dragged in the world, the best I can think of is making a 3D text on top of the object that is visible only in the editor. I don’t think there is a better way.
