Ableton Mixer preset

I have looked at Ableton Mixer preset. Very interesting. I have a couple of questions. Is this preset using Abletons API? If that is the case, almost everything will be possible, right? For example if I need a button that inserts a locator at the current position? Or two buttons that get to the previous and next locator?

The mixer preset works only with the ableton live remote script, see GitHub - xot/ElectraOne: Ableton Live MIDI Remote Script for the Electra One
