Hi, I have tried adding the viewer destroy and it always produces the following error ``` core.js:6014 ERROR Error: Uncaught (in promise): TypeError: e[i].destroy is not a function TypeError: e[i].destroy...

Ah my bad that seems to have fixed it. I have made sure to clear any event listeners, imagery layers and objects added to cesium in the ngOnDestroy()... Great news...

Hi @eitanfr have you managed to get a change to look at this?

Any chance on making the stepService public? It would make custom buttons that need to call next/previous much easier.

Also experiencing this problem and it is fixed with JSON.parse(JSON.stringify());... An optional param for mutability would be nice.

done

Any progress on whether this will be added as a feature?
