Do Not Disturb Button Delay
It is too easy to go into DND and sometimes not realise it.
It would be better if to enter DND mode you had to hold the button for 2-3sec so that it is difficult to do this by accident.
Perhaps a site-wide configuration parameter that "unsets" the DND function after a specified period of time.
Suggestions were 15, 30, 45, 60? Perhaps a profile setting like sleep on an alarm clock could be set by the user on the badge?
