Body

Is your feature request related to a problem? Please describe.
When reviewing large Pull Requests with many files, it becomes difficult and time-consuming to find remaining unreviewed files. For example, in PRs with over 50 files (e.g., 48/54 viewed), scrolling through all the collapsed/viewed files to find the unviewed ones hinders review efficiency.

Describe the solution you'd like
Add a filter or toggle option in the "Files changed" tab to:

• Show only unviewed files (hide files already marked as "Viewed").
• Or filter files by status: All / Viewed / Unviewed.

Describe alternatives you've considered
Currently, the only workaround is manually scrolling and scanning for uncollapsed file headers or using browser search, which is inefficient for large PRs.

Additional context
Having this filter would greatly improve the code review experience for large-scale changes.

@hatasakoyoshikazu-lab We currently do have this capability in the new Files Changed experience. Click the filter next to the file tree, then select “viewed files.” if you want to hide/show them.
