The reason for most of these shortcomings is that the curve docker was designed
to be a generic interface for all kinds of animated properties, but we haven't
had time to flesh out this feature yet. For example, this is why you see
negative values despite opacity only supporting the 0-255 range.

The scale is chosen to fit the curve. I agree this not working well for
opacity. For channels with a well-defined range we should fit to that range
instead.

The first keyframe cannot be added because the docker has no channel to add it
to. We could add a way to create one with the add keyframe button on the docker
much like in the animation docker.

The default value should be the layer's current opacity. This is a clear bug.
I also agree that showing percentages, adding grid lines and allowing scrubbing
by clicking and dragging outside the nodes would be useful.
