unfortunately, this extension makes youtube run VERY slow and it often breaks; ive tried asking for help on the discord server, but i got no response... the userscript version doesnt work any better
also, the extension doesnt work with dearrow and it doesnt work well with sponsorblock

Very nice features, lightweight.
Completely customisable from headers and font, to returning dislikes.
Gamelogging has been discontinued tho.

Pretty nice extension, it was working really nice until it just randomly would pop up the " error has occurred" page whenever you click on a video. Please fix this.

you need to remove public subscribers and show total sub count on channels and add new layouts including 2013 and 2007 layouts

Faster than both Rehike and Polymer, very functional, brings back lots of features that are gone from current YouTube, while having the ability to use a few modern features like Community posts.
There's a few minor gripes I have, like how some caption formats don't display properly and how theres no end screens, although those would probably be hard to implement so it's no big deal.
Some of the links are broken which is a bit of a bother but its not dealbreaking, and I legitimately like browsing on V3 more than I like browsing on the actual YouTube layout. Would recommend to anyone who's feeling nostalgic, hates modern YouTube, or finds the current layout slow.

fixed all of my issues previously. 5 stars!

Best old YouTube layout recreation extension I've seen so far.

Best old YouTube layout recreation, really recommend it and it's customizable

perfect recreation of classic youtube

Finally, youtube is good again!

5 stars in advance for the intention and on the assumption that the development will be completed and continued.

Great, just great, I would give it a 10/5 If i could.

I always dream to going back to old YouTube layouts that I enjoy in the past and thanks to this extension you can and the community is so cool that you can customize with Stylus to make it what ever u what highly recommend everyone tries this so you no longer have to see the boring bland ugly YouTube layout today and can go back to the days when it looked awesome
