page for deciding some action, Completing a form or to view
content.

providing Escape button.

clearly.
- To recover from accidentally closing overlay, the field inputs
should be saved, while completing a form and overlay should be easy
to reactivate..

would perform knowing its consequences.e.g. Linkedin and other
similar websites use 'Yes, Remove them' button to remove their
contacts.
