When a user clicks an event or reaction to configure it, should the connection be disabled during the editing process?
Reasons to disable:
If you accidentally set a timer for 1 second then it will be hard to configure it since the event will be firing every second.
Reasons not to disable:
If you have a timer set to feed your cat every day at 3:00 and happen to open the configuration window right before that, your cat will not be fed and will die.
