Title: [Feature Request] Please add a fixed or favorite function.

🥰 Requirement description

When encountering important conversations, you need to collect them and fix them, otherwise it will be difficult to find them.
It's strange, why such an important function has never been there.

It seems that others have already reported this feature, and I don’t know why I didn’t add it.
