3-way color correction and CC Composite

What I'm missing 3 way color correction tool. I found out that you can do pretty much the same thing using SOP/Sat or 3 point ballance, but these can be somewhat harder to use than having 3 color wheels displayed at once etc so it would be nice to have.

Other thing is to hav CC Composite, which basically just composites the original video with the video using some blending mode.. Again this can be done right now as applying some effects to video and then adding it again to track above and add a transition on the whole length of the video, it would be nice to be able to do it as an effect.
