The extension is just what you need, but there are a couple of small things you might want. I'd like to see the date on the viewed tab. Additionally, I'd like to sync it with your YouTube history to load old data and use it. This would be really valuable.

I understand that the purpose of the extension is to avoid logging in but saving your browsing history, but it would be cool to have the option to log in and sync with your YouTube account.

I mean, it works, but it also tell me on the homepage I watched some videos I know I didn't (video from subscriptions that came out an hour ago).

Installed it , but there are no instructions about how to make this work....nothing. Where is the history held? How do I access it?
