I use chatgpt to understand complex topics and when reading I sometimes do not know a sub-topic and need to learn about that. If i continue asking the question in the same chat window, the chat becomes long and I have to scroll up many times to go to the root topic I was learning. it would be great if we could have a secondary chat window to search subtopics within the main chat window. Think how Kindle uses the dictionary feature, where you do not have to switch your page to access dictionary.
