I had not thought of this situation... Maybe qjackctk should start
itself but just once. That is, if qjackctl finds that qjackctl is
already running and jackd is already running then it bails out (but
starts the app first, of course), otherwise it starts itself (and
"attaches" to the already running jackd if one is found, otherwise
starts jackd as well, same as "-s"). This would be good (that the
qjackctl's gui appears) because then the user has a patchbay ready to
go.

Yup, you got it! :-)
I was thinking (again!!) on the best way to add menu entries for jack
apps and started along the line of "well, a script could be written that
checks for..." and so on. And then I thought "Qjackctl!!" :-)

Hmmm, and all following args, I guess, which should be passed to the
application, right?

Sounds right.
