In the Nxt Plugin (and the Butia) I add the "stop motors" in the stop of the Turtle.When the robot is "crazy" and you want to stop it, the best way (beyond turn off) isclick on the stop button off the Turtle.
The WeDo plugin have the "stop motors" function: when you click on the "stop"of the turtle, the WeDo motor is stopped??
