If that's your goal, then I'd suggest refactoring these listeners. The only
one I see being used outside of the UI is the job progress one. So all the
others could still be kept internal to the UI.
It just feels really weird to be importing a bunch of UI-specific classes
to service functionality that is not UI-specific.
