What's Wrong?

Bug description

After the recent update (around April 14, 2026), the diff view in Claude Code Desktop was redesigned
and moved to the top of the interface. Since this change, only new (untracked) files appear in
the diff panel. Modified files are not shown at all, even though they were clearly edited during
the session.

Steps to reproduce

1. Open a project in Claude Code Desktop (Windows)
2. Ask Claude to modify an existing file (e.g. add a method to an existing .cs file)
3. Open the Diff view (Ctrl+D)
4. Only newly created files appear in the file list — modified files are missing

Expected behavior

The diff view should show all files changed during the session — both new and modified.

Actual behavior

Only new/untracked files are listed. Modified files do not appear.

Environment

• OS: Windows 11 Pro (10.0.26200)
• Claude Code version: [FILL IN YOUR VERSION]
• IDE: VS Code

Screenshot

[Attach your screenshot showing the diff view with only new files]

What Should Happen?

I should be seeing not only new files but also edited files
