Feature Request: “Bookmark & Ask” for persistent contextual conversations in long ChatGPT chats

Yesterday, I was using ChatGPT to learn DSA, and my conversation had become quite long. I got stuck on one paragraph and wanted to ask a small question about it.

Instead of interrupting the main conversation, I thought it would be useful to select the text → choose “Bookmark & Ask” → open a small chat popup beside that text.

I could ask my questions there, close the popup when I’m done, and continue the main conversation normally. The selected text would keep a :bookmark: bookmark, so I could click it later to reopen the same mini-conversation and continue asking related questions.

This could be especially useful for students, developers, researchers, and anyone working with long conversations.

Simple flow:
Select text → Bookmark & Ask → Ask questions → Close → Return anytime

I think this could make long ChatGPT conversations much easier to learn from and navigate. Would love to hear what others think!
