Works well. Only problem is that it causes the entire youtube page to refresh whenever you click on a tab with the sort by oldest button.

It took only a couple of seconds to sort 5 years of videos on a channel so I could see the oldest first (much quicker than scrolling through page after page, thank you!!!)

However when I went back to that page of videos after watching a video, it was flashing and unuseable, so I'd have to refresh it and sort the videos again.

Work-around: Right-click on a video and choose Open in a New Tab.

Just got it, and first impression is that this is perfect. Seamless and quickly goes through the oldest videos the way YouTube should've done from the beginning. Combined with a multi select extension and I can even create a massive playlist so that I can easily go through all of a creators hard work.

Works like a Swiss clock.

Works as good as possible, may take a minute to load the channel's videos but I'd imagine that's as good as it goes. (I too made an account just to rate this extension👌)

Works perfectly.
