• Abbreviated identifiers should have hover over to see the full identifier
• On identifier creation, if there is a failure, supply an error message
• Session can be interrupted while the app is running, this needs a fix or clever way to prompt user to reconnect.
• All screens need a way to notify user if disconnected or some other error.
• The credential 'Select' button needs more padding
• The identifier 'Select' button needs more padding
• Credential 'sign-in' button should not wrap
• The example webapp should navigate to a welcome screen once sign-in successful. The welcome screen should tell the user what they signed in with and display the errors.
