What are/would be the best feature/s on an escalator? See detail.

Speed.
Good brakes.
Spare, safety, cables.
Bouncy rubber block down in the shaft, in case all cables, including the spare safety ones, break.
Desmellarizer.

Cup holders
Dance mats on each step

. . . escalator gang!

Music and fancy lights like Atlanta had on the people mover between terminals

The attendants helping you on and off. Best one is at Snowmass at Aspen, ski on, ski off.

An emergency stop button.
Warning signs to make sure shoe laces are tied and out of the way as accidents have happened because of shoe laces getting caught .
Lights on the sides of each step.
Rules about who or what can and cannot be on the escalator.( pets, wheelchairs, equipment)

Thanks for the non jokey answers.
@rebbel what do you mean speed though? Do you mean the regular ones are too slow? For some people they are too fast they just use the stairs instead.
