How do I hide, delete or manage grease pencil lines in 2.8? I drew on a face reference photo with the grease pencil by holding D. I want to hide the lines I drew. Some sources say to press N and then go to the "grease pencil" section, but that appears to be missing/moved in 2.8. Trying to search for 2.8 grease pencil gives me a bunch of long tutorials on creating 2D animations with the new grease pencil, but not a simple answer on how to hide the lines I drew. How do I hide or manage them?
Grease Pencil became a separate object (and more complex) type in 2.8. If you just draw with D, you now create an Annotation and you can toggle it's visibility:


globally in the Overlays section





individually by toggling an annotation layer in the N panel -> Annotations
