Microsoft has released an update to their Remote Desktop app for Windows Phone. The update, version 8.1.7 for those keeping score, brings the normal bug fixes but also brings a new feature that heavy users will find a big benefit. Now you can pin apps to the Start screen on your Windows Phone.
In addition to this, automatic refresh of Azure RemoteApp has been added to this update for those who use that service.
The app is free and available now in the Windows Phone Store
