Oh I see, yeah that looks really nice, we should do that consistently across all the courses. Something to do in a separate pass I think. Fwiw I didn't systematically do the before/after thing in the RNAseq materials to save time but I really like the look of it. Let's plan to do a campaign to add that in everywhere.

Yeahhh - I was thinking about exactly this as I went through the material 💯

I was wondering if by adding the highlighted lines we could get rid of the "before" / "after" and have only the "after" blocks 🤔 - or perhaps have as a grouped code block with "after" shown by default? Not sure if that's going too far though.

Agree that we should do it systematically, but I don't think it'd take that long to do.
