Slowing the Turning Speed on the Twin Stick Example and Having the mouse be what makes you aim

I’ve used UE4 in the past but it was long ago and I forgot how to do some things. So, I am taking to the forums for answers.

First of all I use blueprints, not C++ or any sort of coding. So hopefully that doesn’t make it harder to tell me how to do this.

I am trying to figure out a way to have the turning on the player not be so instant and rough and more of a smooth transition.
I am also trying to make it so when you shoot it isn’t the arrow keys but you aim with the “MOUSE” and “LEFT_CLICK” to shoot.

Please respond asap as I cannot figure this out at all.
