Not sure if this is a bug or not yet implemented. I would like to see your video cuts match your fader curve. I.e. if my curve is set to FAST then the video fade in curve should match. Currently this doesn't match, if the fader curve is fast then the video is only 100% visible when the fader is right in the middle.

The scratch fader transition makes this better, but it has it's own issue:

i think the video and audio curves should be independent

maybe a preference switch then,
- mimic fader speed
- normal fader speed
