more levels and curves capability

[dts350z]

In the histogram center, could we please have a way to adjust the black and white points, in addition to the two curve adjustment points we already have?

 

In the photoshop curves function, these show as the black and white triangles under the curve, and they are slide-able, but I think the function should actually be more like the triangles in the photoshop levels function.

 

Hope that's clear.

Working with the existing tool some more, I guess having two more adjustment points would achieve the same goal, because you could pull the first one to the bottom and slide it along to duplicate a black point setting, and similar with a 4th adjustment point and the top.

 

Certainly less work to implement.
