Hello!
I’m not sure if it’s a bug or a feature 
There are two scenarios:
- Open ChatGPT (I use chrome), type in a prompt, but don’t send it. Open another tab with chatgpt - the new chat contains the previous, unsent prompt.
- In a “specialized” chat type in a prompt, but don’t send it. Switch to another chat from the list on the left (e.g. Chat about ReactJS switched to chat about C++).
I mean it’s cool that the prompt kept between reloads of the same tab, but I believe it should be cleared when switching to another chat.
