Pin important conversations and add ability to sort/filter conversations

I would like two conversation-management features in ChatGPT: 1. Pin important conversations Please allow users to pin selected conversations to the top of the sidebar or to a dedicated “Pinned” section. This would make it much easier to keep active reference threads, master projects, and long-running research conversations accessible. 2. Sort and filter conversations Please add sorting and filtering options for conversations, including: * sort by date updated * sort by date created * sort alphabetically by title * filter by archived / unarchived * filter by project * filter by date range
