There are several things I would like to see in the "Enhance image" dialog:

A new bar so you can apply a gamma correction (ranging from 0.01 to 10.00).
A checkbox to invert colors (i.e. turning black to white and vice versa).
A checkbox or a button to switch the image histogram to a logarithmic scale.
The histogram should correspond to what you actually see rather than what the original image looks like. E.g., changing the contrast of an image should be reflected in the histogram as well.
A button "Reset" (or something) to reset everything to identity values. (The "Revert" button sets the values to the last saved ones.)
