I can set an XPage as launch page for the application in Notes.
But what happes if a Notes client in basic configuration opens the app? It fails back to the oldschool standard navigator/view layout, which is very ugly. And I cannot display a page with a nice message "this app needs Notes 8.5.2 standard" or something like that.

(Ok, I can add some script to the postOpen event of the view which then opens a page, but that feels more like an hack as an solution.)

So, I would like to configure two launch options:

1.) launch XPage when client version is suitable for the XPage, and the client runs in standard configuration
2.) launch something else otherwise
