Ability to zoom in to curves

The curves feature is fantastic, but sometimes I need more control. The slightest mouse movement can significantly boost colors, and it would be useful to be able to zoom in.

In addition, it would be useful to be able to select part or all of the original frame as a reference point that I can turn off and on to show what it looks like with and without curves.

Absolutly ! +1
Maybe a magnified window, like there use to be in former version of resolve would be helpfull.

There is a panels for precise.
