FumeFX Grid Settings Deep Copy
This script copies settings from one grid to another. It does not touch output paths, size etc, but it'll merge the other parameters from one grid to one or more other grids. Handy if you have a lot of grids, do a change in one and need to apply the same changes to all the other grids.
Current version has a couple of limitations. It does not support copying all effectors and keys from colors.
