I would like to see some more functions on the blend ranges tab, one that would allow an adjustment layer, or any layer, to be applied only to a specific range of colours. The way I imagine it, is that when you press the cog icon on a layer, a colour wheel also shows, pretty similar to the HSL wheel, but you would be able to deactivate certain colours, and adjust the range of the ones that stay activated. By default, every colour would be active. I think it would save a lot of time if you want to apply an adjustment only on a specific colour range, or if you want a double exposure and replace specific colours of the first image with what's on the second image, and many more functions.
