I try it, but it doesn't work correctly. I create 4 Folder and put some Gemini Chats to them. Every time I opened one of these folders the content has changed or go to another folder. Nothing keeps on his place I placed the chat before.
If it would work its a great idea!

I place chats into Gemini in specific folders, and on reloading the page, the chats are often not the same ones, or chats that are in "Unassigned" appear in my folders randomly.

This extension is basically useless. Don't use it.
