MCPE: Better Deploying Elytra Off Ground

I think that its a liitle hard on mobile to fly upwards with an elytra off the ground without gaining any height so I am suggesting a feature to make it easier. If a player is wearing an elytra and long presses the screen with a firework in their hand, once they double tap jumo to open their elytra they will rocket forward in the direction they are facing. You shouldn't have to time your long presses to be able to to this so that it can save us some time from trying to find a big hill to leap off of.
