Make it so the site doesnt go down every 10 seconds. Like seriously. Why does some webpages take MINUTES to load or display internal 500 and my internet connection is decent, Fix your servers.

Improve Cosmic Panda It'd mostly be tweaks probably (like please let us pick channel background colour with HEX, also maybe change the width to be more accurate on YT iirc it was 960 not 1000px) but also please include the 3 other channel layouts included in Cosmic Panda (right now its just blogger)

Allow "Related Videos" to Refresh with Newer Videos Actually Related to What You're Watching It's a bit of a small suggestion, but every day, I see the same stuff in Related all the time no matter what I'm watching, and it would be nice to have it be entirely made of newer videos. That way, it can promote smaller channels who need more views and I can find more people to watch!
