I have modified the aircraft position settings for those airports mentioned in the subject. They can be download from the attachment.
I disabled the marshaller at gates and parkings with visual (guidance) docking system and disabled the staircases at gates with jetways for:
EDDB,EDDH,EDDP,EDDS,LHBP and Heathrow Xtreme V3.
I additionally changed some pushback directions in EGLL to make them reliable. I also assigned GSX a jetway in EGLL where there is one. For EGHI I customized vehicle positions so that the GSX vehicles are not being mixed up with ORBX scenery objects, except for one gate (just too small for baggage vehicle).
In EGLL I had modified some 500 gates and had not the inspiration to test them all. So there might be a faulty assignment. But I tried my best.
