I like the code editor style preview on the right. Enough to forgive the slightly clunky scroll.
It looks nice, but I find the choppy scrolling (on an M1 MBP, no less!) to be distracting.
It also doesn't really tell me anything about the content, except where I'm going to see tables or code blocks, so I'm not sure what the benefit is.
Given the really janky scrolling, I'd like to have a way to hide it.
