I was looking into this sometime back, but I wanted a way to have all ship accel and decel at the same rate, fighters through supercaps. Unfortunately, if fighters and destroyers jump in or out as a group, it would cause each fighter to generate their own vortex, which is definitely NOT correct for B5. You can disable the warp rendering, but it automatically eliminates the associated accel and decel associated with warping. Over the years, I have asked the SCP guys for ways of simply disabling the vortex without losing the accel/decel, but I was turned down each time... though I don't see what kind of relative coding difficulty that would be associated with it.
