I have a suggestion to improve the Yahoo Mail interface.

The Contacts panel currently occupies valuable screen space while reading emails. Since most users don't need to view their contacts all the time, I suggest replacing the always-visible Contacts window with a simple Contacts icon in the sidebar or toolbar.

When users click the icon, the Contacts panel or page can open as needed. By default, the Contacts panel should remain hidden, allowing more space for viewing and reading emails.

This change would:

Increase the available space for viewing email content.
Improve readability, especially on smaller screens and laptops.
Provide a cleaner, less cluttered interface.
Keep Contacts easily accessible without occupying permanent screen space.

I believe this small UI improvement would enhance the overall user experience while maintaining quick access to contacts when needed.

Thank you for considering this suggestion.
