Ability to Launch another application within a PowerApp application. For example, launch Onedrive or any other application from a mobile device on iOS & Android
If you want to launch OneDrive from a PowerApp you can just use the formula Launch("https://onedrive.live.com").
If you are logged in to OneDrive app on your phone and you click on the link in your PowerApp it will automatically open the OneDrive app for you.
Launching an external mobile app (i.e. Dynamics 365 & other external apps) with ability to pass parameters from Powerapps will really very much helpful.
Would LOVE to be able to launch a specific file (an Excel file, for example) and have it print out automatically!!
It will be very interesting to have the possibility to open Teams app
