"Side Chat" to ask quick question without polluting the main thread?

I have this annoying ChatGPT problem: the longer a conversation gets, the useful it becomes because it has all the context. But that also makes me afraid to ask small side questions in it. Sometimes I just want to ask something like: - “What does this mean?” - "Suggest a few alternatives” - “Give an example” - “What's the catch?” - "Simplest way to do this" But asking those inside the main thread makes the conversation messier. Opening a new chat avoids the mess, but loses the context. I kind of wish ChatGPT had a temporary side chat attached to the current conversation.
