It takes 2 clicks to log out and 3 clicks to quit the program and the experience is inconsistent between Mac and Windows.
Mac:
Click Log Out, then click Quit, then click Quit or Close.
If you click Quit the 2nd time, FileMaker quits. If you click Close, it closes CheckIn and you can continue in FileMaker.
Windows:
Click Log Out, then click Quit, then click Quit or Close.
If you click Quit the 2nd time, FileMaker quits. If you click Close, FileMaker quits.
Proposed workflow:
Exit -|
|- Log out (takes you to login screen)
|- Close (closes CheckIn, leaves FileMaker running)
|- Quit (quits application)
