couple more:
44: One more I thought of was building in the fume grid's movement (eg, if animated to track an object) influence on the sim as a slider or pos/rot % slider. So when it's set to 0% it works like a linked/aligned grid with no visible influence on the sim, but maybe you could till keep the buoyance and gravity directions controlable seperately so the smoke still rises correctly etc.
45: if you select knobs within an AFC curve and move them left and right, they scale apart. This doesnt include the knobs at 0 and 1.
46: When you have a large mesh as a deflector (think Ground Plane) or a particle system that extends much further than the grid fumeFX calculates voxels for the whole mesh then culls it to fit in the grid. This can cause huge memory use to calculate the voxels. It would seem more efficient to cull the geometry then voxelize it. Currently we do FFD hacks on the geo to keep it small without changing the topology to preserve velocities.
