Thank you all for the feedback.
I also realize that 3 seconds is very long. It was basically saying ‘3s’ to represent some delay so if we go for the same gesture, it should be shorter than 3s for sure.
Saying that, those designs are proposals that will need to be tested on the real hardware. While the features of the shell may remain the same, the gesture (events) to trigger them is supposed to change if we feel that they are not useful. Waiting for 3s is definitely not useful.
