I'm in the process of creating a game and the scripts are getting pretty big. For more clarity I want to work with the custom editor. But I have problems with types like classes, gameobjects and especially arrays. As you can hopefully see in my picture, it is very easy to make basic types like string and float etc visible. But how does it work with an array ? and especially if the array is still a class or a rigidbody or a gameobject ? I need if possible a good explanation or direct solution. I would be very grateful for your help

Not as nice or neat as Unity's default. But gets the job done.

P.S: You can copy-paste your code when asking questions, rather than posting it as an image. It helps a lot.
