For some purposes I'd prefer 'wait' on a separate monitor. For the
same reason that we sometimes redirect the output of background shell
commands to a file :-)
Solution: 'wait -background' for those async notifications.
Or simply 'notify -background event-type', no need for a wait command
if you give that option.
Or conversely 'notify -channel 1 event-type' to direct the events to
channel 1, and 'wait -channel 1' to show events on that channel.
