I honestly haven’t inspected the nestable.js file in EE4, but in EE3 it’s using the old and no longer maintained plugin. Someone else has forked it and added several useful callbacks and other features. It would be nice if 3rd party devs could use the nestable.js that comes with EE and get access to the callbacks.

Yeah in EE4 it should be largely the same plugin. Since it was abandoned, we’ve been making some modifications to our copy to fix bugs or add functionality, so we currently can’t just drop in a replacement. Which callbacks and features are you looking to use? Maybe we can find a way to merge those in.
