Plans and thoughts for future versions of the Gradation Curves Filter:

• add a Histogram and Levels - important feature
• filter configuration dialogue code cleanup
• make the curve effect visible in the bottom color bar
• more import/export formats (gimp, corel...)
• interpolation when going from pen mode to point/spline mode
• add a better smooth function for the pen mode
• add a direct yuv mode along with the new VirtualDub filter sdk that is available already
• special drawing mode that allows to use different drawing modes in one curve
