Animation: customize bounce interpolation I want to animate a plane falling onto the ground.

It’s good to have the bounce interpolation however you are quite limited when you want to customize it, for example adding more smaller bounces to the end etc, just like you are able to in After Effects.

Is there an addon available to adjust that or is there even a solution within Blender which I just haven’t found?
There is no way to customize them.

The only way out is to not use the premade interpolations. Stay in Bezier interpolation, and use "free" handles to create your own bounces:
