I realize that newbies probably won't get that idea. But it would be great if we can start forming norms around the use of CW like that - Maybe sharing the notion in introductions and incorporating it in crashcourses when saying hello?

The gamedev in me is thinking that adopting/explaining this cultural norm might doublely serve as good opportunity to encourage newbies to play with the CW and visibility controls.

Mostly just floating the idea out there.
