Well, for this adjuster i basically replicated the "Contrast" adjuster that already existed in UIO, since it provided exactly the functionality i wanted (https://raw.github.com/chrispetsos/prefsEditors/master/src/shared/lib/infusion/MyInfusion.js, line 27793). I am not sure how what you are suggesting could be done. This is a repeating enum adjuster and it kind of confuses me on the way it works. Could you provide a sample?
