Why does it need to support a single event

Recently, I tried to make a binding between the YJS and EditorJS.

This is to realize an idea. Please refer to here.

First

Since the synchronization EditorJS changes to the data model (YJS doc) is triggered by onChange.

It is necessary to minimize unnecessary events and avoid performance waste.

Second

In the scenario of multi-person collaborative editing, directly removing and replacing the DOM of the entire block will cause the collaborator to lose the input focus, which will cause experience problems.

Therefore, it is a good way to delegate the work of updating a specific block content to a specific plug-in.

Thanks, @lijie1129, it is nice feature and implementation.

We're working on collaborative editing, but we have not designed Tools API change yet. So adding a update method should be agreed.

Do you have a workaround for a while?
