You can now switch between list view and gallery view in your project dashboard. The new gallery view makes it easier to scan your projects, and quickly locate the one you're looking for.
By default, your Home Frame in the canvas will appear as your thumbnail, but you can also pick a custom one via the new "Set as Thumbnail" menu option. Thumbnails work best as 4:3 aspect ratio Frames—this will make them appear edge-to-edge on the dashboard. Customize your dashboard in the way that works best for you.
