Scale keyframe tangent

I’m animating some UI elements and I’m not satisfied with the default easing of the animation, I could just scale the tangent of the keyframe so it decelerates faster, but I’m unable to do so, only rotate it. Theres some trick to make it bigger?

thx

Nevermind, just saw this in the 2018 beta release log:

Animation: Added weighted tangent support to AnimationCurve.
