Ability to edit "Urgent" chat messages
I like the ability to mark a message urgent, so that it pings for 20 minutes. Currently, however, urgent messages cannot be edited.
Please add the ability to edit the message (this should probably reset the timer -- but maybe not -- others please comment which way you think this should go!)
Please also add the ability when editing the message to remove the "Urgent" flag.
(In our environment, we often need to send a message to a list of many people, but after someone responds, we don't need it to continue pinging those who haven't seen it yet... and we DO need to keep the timestamped text of the message in the discussion so that later replies make sense!)
