I got this great idea when I noticed that nulls were populating my Solids folder. I always reuse solids so why not nulls? But when I pull the null from my solid folder in the project panel it is visible, and in fact it is a solid. I could turn off the visibility, or copy and paste nulls from other precomps, but that's kind of cumbersome. And I could just go on adding my 20th null object. It would be so nice to just pull existing nulls from the project panel. Is there a way?
This script is probably more what you're looking for. It creates one null to use throughout the entire project. Each time you invoke the script, the null is "copied" to your active composition while keeping only one null in the project window. You can set it up as a keyboard shortcut as well.
It only happened to me for the first time. The weird thing is I reuse nulls all the time and never experienced this before. Even in my current project if I drag other nulls into my scene they are not showing, only this particular one.
