Values/indicators for COLOR ENGINE tab

### Feature Request Values shown/displayed for the components in the COLOR ENGINE tab because there is no precise way of knowing the current vale of the adjustment/modification other than the control positions and the image. ### Use Case When working in any module of the COLOR ENGINE tab the only indication of change is the image itself and the UI control, but because of there relative nature it would be usefull to have a precise value shown (it would also aid when using COLOR.io on a smallscreen mobile/touch device because one obscures the UI temporarily when in use. I think there is still space to do so (add values) BUT if if you don't want to clutter the UI with the values One implementation would be to display them temporarily on the image area (over the image) this would have the benefit of mantaining the focus on the image itself but would not give feedback of current value without moving a slider/point..
