In this SharePoint Developer Framework video for office365 we tie together web part properties and use them to filter real SharePoint online data. I can see this being used in real-world scenarios because it gives the end-user more control over the web part (i.e. which web to select and how many Lists to display). Also, we will take a look at the Slider property (which is way cool and easy to use). This is a great video that ties together all what we learned in the previous video and put it to work in a real practical use for some of the most requested capabilities when developing custom web parts. P.S. I feel developing this web part in client-side code (.vs in a WSP or app part) the process is a lot easier and the development cycles are short and fluid. Check out the walk-through now. ?
