I sometimes run across an Inventor user that has played around with some of the "settings" and now they can't clearly tell which part they are editing in the context of their assembly. This is usually due to the "Component Opacity" setting that is commonly overlooked (or turned on without knowing what it does). Take a look at the following video for an example of the component opacity as well as another overlooked visibility option.
