Allow pinning and also categorizing (or foldering) chat in ChatGPT GUI

Hi there, please add chat pinning and custom categorization to the user interface (GUI). In my daily routine using ChatGPT, I often need to refer back to specific chats. If I could pin those chats in the GUI, it would be a very useful feature. Additionally, allowing users to organize chats with custom sorting or categorization would also be greatly beneficial.
