I found an app that makes your smartphone an extension that gives you the ability to control the PC applications or games. It could become an add-on screen for an additional view in the flying simulator or an extension of the control pad can also be used to do all kinds of functions, too. It's based on two main components: the PC app and the mobile phone app. These two work together to deliver you thousands of shortcuts or functions that can be found in Gallery.
What if we had online cloud-based Windows, Linux, or Mac accounts and environments that you can log in and use from any PC, laptop, or another machine? You would log in by verifying your identity by smartphone and use your smartphone for further security or important steps, as well as a way to control the machine (mouse, keyboard, additional screen, etc.). Is something like this already available?
