With this update, you now have the ability to access the Fn keys as part of the extended keyboard. Simply tap the FN button to show or hide the Fn keys (F1 through F12). On top of that, Microsoft has improved the overall experience of the app -- especially the in-session experience. This is what Microsoft had to say:
"As we prepare to support multiple simultaneous sessions, we are making some changes to the way we handle session disconnection. With today’s update, you will not be required to press the Back button twice to disconnect the session and go back to the Connection Center. Instead, pressing back once will return to the Connection Center but will leave the session active. Tapping the same desktop tile will quickly jump back in the session while tapping on a different desktop will disconnect the existing session and connect to the new desktop," Microsoft stated in an official blog post.
In order to disconnect from a session, just click on the Connection Bar at the top of the screen to show additional options including the active sessions and the ability to switch between Touch and Mouse Pointer input modes on the right.
Remote Desktop also supports a new Cortana voice command to quickly add a new desktop connection. Just say "Remote Desktop add [a] [new] desktop" and you will be taken to the ADD DESKTOP page where you can enter the PC name, tap save and then start the connection by tapping the newly created tile.
Microsoft has also added a link to the feature request site within the app, so you can easily be taken to the feedback site to recommend improvements to the app. The link is located in the About page.
