Exiting the custom detail screen exits you completely out of an employee instead of taking you back to the detail icons
Once in a custom detail panel, when you click the red X to exit, you also exit the View/Edit employee back out to the menu. If you wanted to go to another detail page on that employee, or if you wanted to go to another employee, now you have to click on View/Edit Employee from the menu and start over. When you exit a custom detail panel, it should move you backwards through the options so you can choose a different custom panel or a different detail page altogether, instead of kicking you completely out of the task. On the regular detail panels you have the option of Apply which leaves you in that employee, but not so in the custom details.
