Feature request: Diff preview + granular accept/reject workflow in OpenAI Codex VS Code extension

Hi @isaacT, this is a really thoughtful suggestion, and honestly, a fair one. Right now the Codex extension applies edits directly, which is fast, but as you pointed out, it can get hard to track what changed once the edits get larger. Especially in professional workflows, being able to review a diff before changes land is pretty important. There isn’t currently a built-in “preview before apply” workflow in the extension, but the idea of diff preview + selective acceptance makes a lot of sense. I’ll make sure this feedback is captured, particularly the integration with VS Code’s native diff UI, which would feel very natural. Appreciate you laying it out clearly. This is the kind of UX improvement that can make a big difference in day-to-day usage.
