Overlays in prototypes
You can now turn any Artboard into an Overlay and create interactions like sheets, popovers and modals in your prototypes. You can set the position of an Overlay relative to the screen it appears on or the layer that links to it. You can even ‘stack’ multiple Overlays, choose how they interact with each other, apply background styling, and even block background interactions. You can view prototypes with overlays on the Mac, web and our new iPhone app (but they will not work in the Mirror).
Prototyping improvements
Along with Overlays, we’ve added a Prototype tab to the Inspector for all Prototyping-related controls. Switch to this new tab to see all prototype interactions in a document. Switching back to the Design tab will hide them until you select a layer. When you switch to the Prototype tab and select a layer, you’ll see a new + icon instead of the middle-right grab handle, click and drag on this to start creating a new prototype interaction.
Auto-download Libraries
You can now set Libraries to automatically download whenever an update is available, so you can skip to the good part (reviewing and updating your Components). You’ll find the option for this in the Libraries Preferences pane.
