Feature Request: Option to hide auto-expanded diffs

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

Summary

Add a setting to show only file edit summaries without auto-expanding full diff content.

Current Behavior

When Claude edits files, the UI displays full diff output showing all changed lines, creating excessive scroll when many files are edited.

Proposed Solution

Requested Behavior

Option to show only the summary:

Update(file.py)
  ⎿ Added 3 lines, removed 1 line

With diff content available on-demand (e.g., ctrl+o to expand).

Use Case Example

Use Case

Sessions with many file edits create visual noise. Useful for users who:

• Make many changes per session
• Trust Claude's edits without reviewing every diff
• Want cleaner, more compact output
• Optimize for minimal visual clutter

Suggested Implementation

Add setting in ~/.claude/settings.json:

{
  "autoExpandDiffs": false
}

Current Workaround

None - diffs always auto-expand.

[Please note this request was generated by Claude Code, so if it's too fancy, don't blame me. ;-) ]
