pass -n argument to ``ofm status``

I think it's possible to pass a -n argument to systemctl status to change the length of the log. This is really handy when debugging a failed server start. Could that be passed through from ofm status? Similarly, journalctl -u openflexure-microscope-server.service -b gives a scrollable (piped through less) view of the whole log since the last boot - remove the -b flag to get the whole log. That is different from ofm log becuase the latter doesn't get the stack trace if the server crashes. Could we add a wrapper for that?
