Many thanks for the clarification! That’s what I thought initially, but got confused by the recent discussions. My main point is, that it can be practical to offer a standalone app or at least the user experience of a standalone app without telling the user “Hey, to use our app switch over to this other app called Launcher and enter your login data there.”
This is a drawback, yes, but may be acceptable, because you have to log-in in many other apps (Dropbox, Google Drive, etc.) too currently.
Concluding this discussion I see two possible options in the future to build seamless integrated apps:
1.) Create possibility to start launcher with credentials parameters and/or put it into auto-start with an option to store the credentials locally. So apps could wait until the launcher is available.
2.) Integrate launcher functionality into own app with the mentioned drawbacks.
@dirvine would be very interesting to hear some thoughts if option 1 is something which is planned (or at least considerable)
