Gippity Pruner - fix long GPT chats

Gippity Pruner is a simple tool that hides your older ChatGPT messages from view and eliminates UI lag in long chats. Gippity Pruner only shows you messages that you want to see. This extension does not delete any messages, it just hides them from the chat view. Since ChatGPT still stores the full conversation history, you can still disable the pruning feature and see all your messages, and also get the full context in your responses. Pin Messages! You can also pin messages you want always in your conversation history, without needing to scroll way back up again and again!
