Juergen,
    With all the related requests about this, it is actually a bit 
complicated.  The state
engine needs to be able to handle waiting for multiple external 
processes to complete.
I will give it some more thought.  I like your ideas here,

    There are a few related Feature Requests that are already open:
https://sourceforge.net/tracker/index.php?func=detail&aid=926800&group_id=39428&atid=425190
https://sourceforge.net/tracker/index.php?func=detail&aid=837037&group_id=39428&atid=425190

    I added this mail to first feature request.

Cheers,
Leif
