Feature Request: Selective Context Management / "Forget this Block" Option in Chat History

Currently, Gemini uses the entire recent chat history as context for subsequent responses. Sometimes, a specific prompt or output deviates from the main topic, which skews future answers unless the entire chat is deleted.

Proposed Feature: Introduce a “Remove from Context” or “Forget this Block” button for individual messages/outputs. This would allow users to surgically remove a specific interaction from the active conversation’s memory, ensuring that future outputs remain accurate and unbiased by irrelevant previous context.
