What I do is create a copy with identical pesets right next to each other in the 'my filters' column.....work on individual copy settings and visually compare the presets by clicking back and forth between filters.....then delete the original when the copy has reached a marked improvement after randomization testing.....then repeat the process for the next level of improvement to the filter.....
I think that having lockable controls to zero in on problems through randomization would make filtermaking really slick.....
