Tile and Splash Screen
The App Bar is typically shown on the bottom of applications, but I thought it worked better at top in this case. If you find yourself using the App Bar a lot, which you might when heavily editing tasks, you can pin it in place.
The commands at the right of the App Bar allow new projects to be created, existing projects to be opened, and projects to be saved. There’s also a Sample button which loads a sample project of tasks, making it easy for the application to be demoed.
