Feature Request: Inline Tooltip Explanations for Selected Text

Problem:
• Currently, when you highlight text in a ChatGPT reply, a quote button appears, allowing you to reply to a specific piece.
• This is convenient, but leads to long, nested threads and requires a lot of scrolling.

Proposed Solution:
• Add an “Explain” button that appears when you highlight text.
• When clicked, a small tooltip opens (similar to Wikipedia preview cards).
• The tooltip contains a short explanation (up to 300 characters) without breaking the flow of the conversation.
• The feature complements, rather than replaces, quoting — quotes are saved for deeper discussions.

Benefits:
• Less scrolling — explanations are available instantly, without creating long threads.
• Cleaner interface — discussions remain structured and easy to read.
• Quick access to context — clarifications are received in seconds without losing the thread of the conversation.

Additional:
• UI mockup included for clarity.
• Open for discussion and refinement of the idea.
