I love Color Levels, I use it all the time. Yet there are situations where I feel I would need more control.
It turns out that if the colors I whant to modify have not constant lighting it is very easy to end up burning lit colors if dark colors are too dark. I wish there was a dropdown so, similarly to Image editors you can modify only highlights or shadowed areas. I can manually do so by using Composite SF and cutting so I choose the dark area and split the cloud and modify that cloud and merge back. Wish this could be streamlined a big by adding a dropdown like "shadows" or "highlights" or even have an slider to visually see the area to be modified.

SHADOWS BRIGHTENED WITHOUT BURNING LIT AREAS
Also, something I would MUCH, MUCH MUCH appreciate if there was a "preview" checkbox because otherwise it is a somewhat wild guess on how the colors will be modified, despite the graph.
