Only allow one component to be dropped
Question
Sorry for the newbie question, but say I have a text field component and I only want to allow the user to drop a specific number of them into the canvas, say just one. How do I limit it? Perhaps a way that shows an alert to explain they cannot add another text field component to the canvas unless they remove the existing one?

So I have a very ugly solution right now: This basically looks whether the component is in the canvas on load. If it is then it hides the draggable component button - Here I could use a better way to hide the button - how? I can get to the component with const form = editor.BlockManager.get('form')...
