I think Scratch should add a new boolean block called “I receive message ( ) ” ( ) being where you can choose one of the messages you made. For example, It would be useful in a situation where you would want to repeat something until you receive a certain message. If you make it, I think it should be in Events. I hope you take it into consideration (because I could really use that block right now).

This is rejected because what would happen if the brodcast fired multiple times? A repeat until broadcast block or a broadcast received in the last __ seconds is not rejected though. Scratch on! –Explosion–
