That might work. You could also pass that information to the update callback.

Right now, if I simply change the selection the update method is called. Use Case If the user moved an rectangle then I want to know that the document has changed. If the user simply selected a different rectangle then the document has not changed and I want to avoid running any specific operations. async update(type) { if (type=="selection") updateUI()…

In that feature request when update was called it would tell you what action initiated the call. You could probably have a second optional parameter that is if the action is undo or redo or first time.

```
function update(type, history) {
    if (type=="selection") {}
    if (type=="move" && history=="redo") {}
}

```
