What information can you see when hovering over an email icon in email threading visualization?

When hovering over an email icon in email threading visualization, you are presented with a tooltip that typically shows sender details and attachments. This feature is designed to provide quick access to essential information without requiring the user to open each individual email. The tooltip enhances user experience by enabling them to see who sent the email, any included attachments, and possibly some additional context about the email's delivery, all of which are useful for navigating through email threads efficiently.

The other options, while relevant information they might seek, are not typically displayed in a standard email hovering tooltip. The subject line is generally visible in the email list or thread view rather than in a hover tooltip. Similarly, details about the distribution list may not be available directly from hovering over the icon but could be found elsewhere, and sentiment analysis would require deeper content processing that goes beyond what hover tooltips are designed to provide.
