When using AddAnnotations API, the Undo icon appears.. but I'm loading annotations in from my servers database...

2. Undo/Redo

When I save the comments my server and reload them on a different computer, the "undo/redo" buttons appear immediately, and I can undo all the previous comments added from other users. Is there any way of blocking this?

Why are you able to undo annotations that werent inserted from the user? The undo button appearing is incredibly confusing for users who never added any annotations. What is there for them to undo??

Why is there two methods for AddAnnotations and AddAnnotationsInPdf also?

I think that in a lot of cases where you are managing storing of the PDF annotations and updating using your own system, you don't actually want the undo/redo feature at all. For example, it is quite difficult to safely handle the cases where a user deletes another user's comment and then undoes this delete.

I would love an option that allows it to be disabled entirely, or disabled by default when

enableAnnotationAPIs is active.

Additionally, it doesn't make sense that any annotations added by annotationManager.addAnnotations get emitted as

ANNOTATION_ADDED events. Or if so, there needs to be a way to detect whether the item was added by the system or by the user.

In regards to the event firing: Honestly I don't agree. If I tell the system to let me know when an annotation is added, no matter what the source. In the end, I'd rather the code always run and use code to programatically ignore when necessary. In this case (and I haven't looked at the code in an annotation object in a while), I'd imagine you could look at the timestamp.
