Enhancement: Add a new line for "Answer" part of gemini-2.0-flash-thinking-exp

[Originalimoc]

What features would you like to see added?

Currently the answer and thinking are concatted without even a space. Add a new line would make viewing much better. Even better, consider add "\n## Answer\n" markdown to seperate them.

Which components are impacted by your request?

UI/API

Should be directed to the API Provider (Google). I have no control in this, and in my experience, sometimes it does this in the response anyway

You actually can do it.
1/ The v1alpha REST API and GenAI SDK( https://ai.google.dev/gemini-api/docs/thinking-mode )(Python though😅) has a parameter stating if current response delta is a thought or not.
2/ The "choices" length is different too, along with v1alpha API:
