Works as intended thanks. Do you think you could create something like this for the channel feed too?

I wish. The only reason this works is because YouTube happened to put the information we need inside the video page itself, in a way that can be accessed by a simple stylesheet. They don't do anything like this for thumbnails in channel feeds, unfortunately. I don't know why they think putting "2 years ago" on dozens of videos is helpful to anybody. Oh well, at least they fixed sorting by oldest first.

Ah, okay, thank you.
