The “echos” are the concept behind
Hype GlobalBehavior. They form the unified layer of behavior. As said this is done to avoid disturbing local functionality and specially infinite loops.
“Echos” is therefor the wrong term in the sense that global behavior changes the custom behavior by adding a # in front. I could also have added an other string. I might even add an option to set the added string to something individual. Maybe something like
global_ could help understand it better.
