If you want to change that kind behaviour for now, you'll have to  
install faust, edit and correct the jack-gtk.cpp wrapper file (located  
in faust/architecture). Then install faust again (since "install" copy  
the architecture files at proper locations) and recompile your jack- 
gtk faust programs.
We may improve the jack-gtk.cpp wrapper file later on to add auto- 
connect and state location options.
