It'd be very useful if we could "solo" video track(s) the same way we can solo audio tracks. Right now, I'm flattening a sequence down to only the archival used. I have a REF with Difference Blend on the top video track to double-check if there are instances where two pieces of archival on different layers are being used (ex. as a split screen). There are many cases where I run across a discrepancy and want to just see the REF to see what things are supposed to look like. It'd be helpful to be able to solo the video track the REF is on rather than needing to keep turning Difference Blend on & off. I have Difference Blend & Normal Blend mapped to my keyboard, but I have to do this often enough that soloing a video track would be helpful.
