Hello! I realize this is a bit of an odd request, but I think it’s worth to ask nonetheless. I think it would be great if you could drop images/textures into the blueprint editor, for pure reference or documentation. Sometimes when Blueprints become tangled and complex it becomes very difficult to read, so being able to drop in a reference image would help out a lot. It would be great if I could pop in some UML right in the middle of my blueprint spaghetti to help me work. This would work great for materials as well, for instance (gotten from http://michalorzelek.com):
It would also bode well with marketplace content for documenting better.
Just a thought 
Thank you!
