Feature request: extend plan-mode's inline-comment review UI to arbitrary markdown files
Plan mode (in the VS Code extension) lets you highlight a portion of the rendered plan and attach an inline comment before approving — feedback anchored to the exact spot it applies to, rather than describing the location in prose back in chat.
It'd be valuable to have that same interaction available for any markdown file Claude is iterating on with you, not just plan-mode's plan artifact. Concretely: a long-form document (e.g., a Method-section draft, a design doc, a research writeup) evolves over a long session through many rounds of feedback. Right now the only ways to give spot-specific feedback are:
- Quote the passage back in chat and describe where it is (works, but loses the direct "point at this exact spot" precision)
- Manually type an inline marker/comment into the file yourself and ask Claude to look for it (works today with zero new tooling, but requires opening the file in an editor and typing the marker by hand — no real UI gesture)
Neither is as fast as the plan-mode experience. A general "annotate this file" mode — even scoped to files Claude just wrote/is actively editing in the session — would remove a lot of friction for iterative document work that isn't code implementation planning (specs, research writeups, decision records, etc.).
