The Dingus currently requires a close and reopen cycle to reflect changes made
to Conductor rules. If you modify a Preprocessor or Processor rule while the
Dingus is open, the Dingus buffer doesn't update until you close and reopen it.
A live update mode, or even a manual refresh button, would make the Dingus much
more useful as a pipeline testing tool, since you could iterate on rules and
immediately see the result without the close/reopen cycle.
