This wound up being a much longer post than I originally intended. It starts off pretty basic for new users, but advanced users should stick around to the end. There will likely be a few things you didn't know you could do.
Let's build a List. (I'm not going to discuss all of the possible options. There are just too many. Nor am I going to try to make something beautiful. This is just an overview of the options available to you.) I started this project with the Jewelry Box Template so it's already got a List widget with a template. If I want to change the template, I can pick a different one at the top of the Settings panel.
