Forces 6 videos per row, adjusts text sizes, hides checkmarks, adjusts spacing.
THIS CODE IS OPTIMIZED FOR OPERA GX IN MIND. Have not tried it in other browsers.
So this code is possibly a final version of exactly how I want Youtube to look, properly 6 videos per row on feed, the correct spacing between elements, nice text sizes and all that.
I'm sure I will update it for more changes but this seems to be it.
I HAD to do this because for SOME REASON OperaGX doesnt like my previous script doing the same thing, so I had to start again. And i'm using OperaGX because Firefox performance on youtube is so bad. Youtube itself is so bad I can't wait for someone to make a proper good page to watch videos.
