Flexible Template
This is a new script template option with minimal instructions. It's useful if you already have a specific structure in mind for your videos, or if you find the preset templates like Educational or Documentary are getting in the way of your writing. It's also recommended if you are remixing a video, since the video itself will have a lot of structure to analyze.
"Clone from Video" Template
When creating a new template, you now have the ability to generate it based on one or more existing YouTube videos. This basically allows you to clone the structure of those videos to create new scripts with the same structure. You can enter a single video, or up to 5 videos. I personally believe less is more in terms of the number of videos to analyze - but the option is there.
Starred Research
You can now star your research sources so they are added to your chat threads automatically. Starred research lives within the context of a channel, meaning it is basically like your global knowledge for the channel itself. This is super useful especially for educational channels where you want to always have some knowledge available about who you are and what your channel is about.
