color grading feature request

I have two feature requests related to color grading.

• One wheel
  • Currently, color grading is done on three separate wheels for each tone (highs, mids, shadows).  I think it would be very useful to have an option to use 1 wheel to place all three grading points (like how DXO photolab does it).  This would be very useful when grading using specific patterns (Y, triangle, line, etc).
• Pre-made pattern options
  • If the one wheel feature is implemented, having a dropdown where we can choose a specific pattern (Y, triangle, etc) would be very useful.  I could choose triangle, for example, and the three grade points would be placed onto the wheel for me.  I could then turn the triangle to find the right mix of hues, and all three would turn at the same time, keeping the triangle shape.  Then I could adjust the saturation of each independtly to taste.  The dropdown could include all the color grading patterns that the adobe color palette site has (I think they are called color harmonies), and it could have a custom option if I want to create my own grade.

I feel like these could help speed up the color grading portion of the workflow.
