I need to be able to write more functions and specifications on Figma Design, because in this way, the project can view pages and specifications at the same time, and does not need to switch to other files (Word, ppt) to view FRD or PRD. 

The designer does not need to switch to the platform to write files, and can collect the above text AI into an asset of internal business logic.Or you can import these specification text into Confidence / Jira /Word. I often have to copy it to all other collaboration tools after writing it in Figma. It's really tiring.

Why is Annotation not enough? Because the text cannot disappear when the case is finalized, and it must be output on the page

At the same time, it can switch to display and hide everything, and provide it to different users to view. The function can be attached to Instance without having to pull a lot of lines to the Note next to it, which is really time-consuming.

Finally, it is recommended that these texts can be copied once by Figma Make.
