I just had a real good look thru the JO weapon.DEF and found these new flag commands.
flags AbsorbPitch
flags 2DImpact
flags NoMove
flags NoCardSwitch
flags ForceCrouch
flags OnlyScoped
flags OnlyFireScoped
flags UseDesignator
flags UseSpreadTwo
flags ShowImpactDist
flags Thermal
flags FixVerticalOfst
so there's got to be more to it. I'll keep a look out
