When users currently login to a FileMaker database, they are presented with a login window that is branded to FileMaker.
In File Options menu, we have the option to created an icon to be shown in the launch centre.
This icon should be used to in the login modal.
This would give a great user experience, much like the FM iOS SDK app has provided the way for a client to have an app tile on their iOS device.
Could even extend this to create a name of the app, rather than the filename, as sometimes this may not be a customer friendly name, as per images attached.
