Let me in-line comment on plans. TLDR: a PR-like commenting flow on claude plans

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

I heavily rely on claude planning agent for complex work, and the generated plans are frequently long and complex. It would be amazing to be able to add comments to a plan as I'm reading through it (similar to commenting on PRs in github or commenting on specific document sections in google docs). This would really speed my ability to steer claude's planning.

Proposed Solution

Allow me to move my cursor through the plan and hit some hotkey for inserting comments at any point. then, when i'm happy just submit the plan. The interview questions you have could actually be interspersed with the plan so that the user could view claude's question in the context of the plan. Then completing an interview would feel like responding to another reviewers comments in a pr while adding my own.

Use Case Example

Here is a snippet from an actual plan I'm looking at inside of claude code right now

 Event Detection

 1. Sort history by (profile_id, history_date)
 2. Compare each record's account_active_through to the previous record's value
 3. Forward movement: Close current subscription at history_date, start new one
 4. Backward movement: Update current subscription's end date
 5. No change: Skip (no subscription event)

What I would love to do:

 Event Detection

 1. Sort history by (profile_id, history_date) 
 2. Compare each record's account_active_through to the previous record's value
 
 ^^^ MAKE SURE YOU ARE ONLY COMPARING RECORDS FOR THE SAME PROFILE ID
 
 3. Forward movement: Close current subscription at history_date, start new one
 4. Backward movement: Update current subscription's end date
 5. No change: Skip (no subscription event)```




### Additional Context

I'm an avid vim user, so having a modal editor where i can scroll around and insert edtis where I want feels natural, but I wouldn't want to horrify the non-vim-using masses, so I am not opinionated on ux.
