The callback setHistoryIndex(prev => prev) is a no-op that returns the same value. When removing the oldest history item, the index should be decremented but is handled incorrectly. The logic should be moved outside the callback to properly update the index after the history array is modified.

Remove TODO-style comments from production code. Either implement the toast notification feature or remove the comment.

Suggested change

// Could add a toast notification here

The property panel header uses min-w-0 which can cause text truncation. Ensure screen readers can access the full component type and ID information even when truncated visually.

Suggested change

	<div className="px-5 py-4 border-b flex items-center justify-between bg-gray-50/50">
	<div
	className="px-5 py-4 border-b flex items-center justify-between bg-gray-50/50"
	aria-label={`Component: ${config?.label || selectedNode.type} (type: ${selectedNode.type}, id: ${selectedNode.id})`}
	title={`Component: ${config?.label || selectedNode.type} (type: ${selectedNode.type}, id: ${selectedNode.id})`}
	>

Using -1 as a magic number to represent 'append to end' is unclear. Consider using a named constant or undefined/null to make the intent more explicit.

Function name getComponentscategory has a typo and should be getComponentsForCategory or getComponentsByCategory for clarity.

Suggested change

	const getComponentscategory = (categoryComponents: string[]) => {
	return categoryComponents.filter(type => ComponentRegistry.getConfig(type));
	};
	const getComponentsForCategory = (categoryComponents: string[]) => {
	return categoryComponents.filter(type => ComponentRegistry.getConfig(type));
	};
	/**
	* @deprecated Use {@link getComponentsForCategory} instead.
	* Backward-compatible alias kept to avoid breaking existing call sites.
	*/
	const getComponentscategory = (categoryComponents: string[]) => {
	return getComponentsForCategory(categoryComponents);
	};
