ICYMI : Gemini Notebook got a new usage limits system, usage estimation for artifact generation, and a background queue for generations when you are out of quota.  

> Limits refresh every 5 hours - Instead of refreshing every 24 hours, your limits now refresh every 5 hours. Get continuous allocation throughout the day.

> Create more of what you love - We are replacing limits per feature with a flexible Notebook-specific limit. You control how you want to spend your limits.

> New background queue - When you are out of limits, you can defer generating videos, slides, etc. for later. These will generate automatically for you.
