Feature Request When actions are disabled and user tries to subscribe to them, they get warned

- Either i was in such a hurry that i didn't read the documentation properly, or the documentation was unclear about it. The third party guide mentioned that actions and maps will not work if they are not explicitly enabled. However, unity and visual studio are silent about this no matter what. I would like to get a warning every time i fall into this trap again so i don't have to waste another couple of hours trying to figure out what's wrong
