A better interface for code review would be a pseudocode layer that sits on top of all of your code, at the editor level.
Basically it would convert all of the chunks of your code using an LLM to simple pseudocode with clickable symbols so you can follow function calls, definitions, then you could expand/collapse it to see the real underlying code.
It's easier to skim pseudocode than it is to reason about complex logic. When I say pseudocode I'm talking very high level but structured explanations, and less the sort of traditional pseudocode you'd imagine which is basically just a generalization over syntax.
