On undo/redo events https://grapesjs.com/docs/api/editor.html#general you can use Undo Manager APIs https://grapesjs.com/docs/api/undo_manager.html

@artf If the undo event needs to be triggered to present it's data, then how can we render or disable the undo/redo btns? Out of the box the Undo/Redo buttons will clear out an entire template if the undo/redo event hasn't tracked anything. I am trying to conditionally render the undo/redo buttons based on there being anything to undo/redo. I am having trouble with the general event "Update". The Update event never seems to be triggered. Can you provide a little more context?

You can use the Undo Manager APIs wherever you want, I didn't say you can use it only after undo/redo events.The Update event never seems to be triggered The update event was added in https://github.com/artf/grapesjs/releases/tag/v0.14.55
