SmartArt and the new Designer feature in Office 365 are great for simple lists, but numbered lists are another story. Designer has a few options, but you can easily create a couple of templates for beautiful numbered lists and use them over and over. Start with a simple list, like this one. You can have as many items as you want, but too many will make the slide cluttered. Here, I numbered the list, but you’ll lose the numbers in the next step, so it isn’t necessary. You can use a bulleted list.
