We're very happy to announce that the new CloudShow Windows client supports per-frame scaling. Set the value to 50% to shrink your content by half, 200% to double, or any other value you need to get your content looking perfect. We have also added controls to everyone's device management page to allow you to refresh or update all devices with one-click.
See all the apps available for CloudShow on the Apps & Content page. Looking for an app we don't yet support? Let us know!
