If you have a lot of subscriptions on YouTube, you know that it's hard to keep your sanity with the current interface, let alone the constant stream of user-hostile changes coming your way.
Now, you could use a browser script to make the horrible "feeds" page a little easier on the eye… and always play catch-up with YouTube, or you could use YT Sanegrid.
Here is why it's better than a browser script:
Don't worry, nothing is stored on a server because this page works completely from (and only stores data in) your browser.
The account that you entered has their subscription list private. If you own this account, you can go to your privacy settings page at https://www.youtube.com/account_privacy and make it public.
The account you entered does not exist.
All code is free and open source software. If you want to help out by filing a bug report, a feature request, or if you just want to check out what is going on while I'm working on this, feel free to check out the project on Github:
