Improved version of the old "Emails" quick search functionality in Gmail, one click to view all emails you've sent or received from any address
This userscript restores — and improves — Gmail’s missing “Emails” search feature.
In the past, Gmail let you hover over a contact’s name, wait for the hover card, and click “Emails” to see every message you’d exchanged. That option is gone — but this script brings it back, faster and better.
With this script installed, a search icon appears next to every contact’s name or email address. Click the icon to instantly search for all emails to or from that contact — no waiting, no copy/paste, no menus.
The icons appear:

First, install a userscript manager extension for your browser:

Your userscript manager will prompt you to install it. Click "Install" to confirm.
Visit Gmail and you'll see search icons next to email addresses. Click any icon to instantly search for all emails with that contact.
The script will automatically update when new versions are released.
