[QUESTION] Best way to listen to changes on the final HTML?

Hi,

I just had a quick question because I could not figure out how to do it or did not find an issue related to it.

I am just trying to call a function when any changes is done on the canvas.

For example, I am adding a block or removing a block. I am changing the attributes using the style manager. Or drag and dropping the blocks within the canvas. Or even updating the traits.

Is there a global event I can listen to it trigger my function?

I am not talking about any actual changes in the Canvas itself but changes that apply to the final HTML when I call the method editor.getHtml().

Any help or guidance is appreciated, thanks!

Update:

For the moment I figured out I could use the storage manager to achieve this, by doing:

storageManager: { type: 'onChange'; }

and 

editor.on('storage:start', callback);

If there is a simpler solution without having to do it this way, I am open to suggestions.

Thanks!
