All logic should be there
I tested adding an image strip and tweaking Saturation and Multiply, and it doesn't seem to be updating? Only when changing frame.
I think this is for metastrips indeed, guess it should be kept.
Looks good now.
Tweaking settings in the adjust panel is much smoother for me now, both compared to master and 2.7. Great work.
