Scalable UI, so I can make a really big curve if I need the precision.
Actual bezier curve!
Ability to make straight lines between points, not just auto-curves...=20
you used to be able to shift-click with a pencil tool to draw straight=20
lines, now it's much harder. (straight lines are useful for graphic=20
effects like posterizing.)
Histogram display, toggle between source and result... Simultaneous=20
display of red, green & blue channels as an option, so you can see how=20
the channels differ.
I once contemplated designing a curves tool where the UI actually=20
appeared in the comp window, so I was adjusting a giant curve right over=
=20
the video. I thought it was a cool idea but not sure if this is worth=20
exploring?

I'll post again if I think of more...
Brian
