I have an idea for look design. Because we can't individually change LUT opacity settings, it's more difficult to merge in one multiple effects layer. If we could individually change LUT opacity sliders one by one it would be a lot easier to combine different LUT's to create the look we want. In short, I think it would be a good idea to add opacity sliders to LUT layers. Also next and previous buttons to go back and forth in LUT's in the folder would make my life a whole lot easier.
