Just wanted to make a suggestion for future releases of C2 to add to the growing list.
I know I would use more color correction effects a lot if they were in there.
A set channels option, curves editor, hue/saturation, tint, levels etc. That in combination with more blending modes, like the current additive, but also including multiply, screen, color burn etc would be absolutely amazing additions and really open up the options for making your games look pretty.
Not to mention the possibility of anaglyph 3D games with very little effort. Ooh, I like that idea :)
