I love the hover previews for Lightroom Classic CC’s profiles and presets, and would LOVE to see it implemented for tone curves. I try to name curves descriptively, but at some point the names overlap and are more relative that helpful. I often find it easier to use a saved curve than start from scratch. I could make presets instead of (or in addition to) saving tone curves, but that seems like an extra step when I want to save the curves for use in Camera raw.Maybe since it’s implemented in other places it won’t be so hard to add it here??
