ChatGPT should remember a user's settings

Suppose I am using the GPT-4 Plugins. As soon as I start a new chat, it will always go to GPT-3.5. I have to click GPT-4 again. That is pretty annoying.

If I reopen the browser to use ChatGPT again, I have to click both GPT-4 and Plugins again. Even more annoying.

Please fix that.
