Remove commented-out code blocks. These appear to be related to unused checkbox functionality and should be cleaned up.

Remove commented-out code. If this padding adjustment was intentional, either apply it or remove the comment entirely.

Suggested change

// center.setPadding(new Insets(0, 0, 0, 8));

ResourcepackFile.parse() can return null, but this code doesn't check for null before creating ResourcepackItem. Add a null check to prevent NullPointerException.

Suggested change

	itemsProperty().add(new ResourcepackItem(ResourcepackFile.parse(path)));
	ResourcepackFile resourcepackFile = ResourcepackFile.parse(path);
	if (resourcepackFile != null) {
	itemsProperty().add(new ResourcepackItem(resourcepackFile));
	}
