Its about time. The Youtube UI has become a disaster over the last few years. It all started with the ability to let uploaders "annotate" their videos. I've disabled the setting to show annotations probably a dozen times and they keep coming back. I can't figure out if the setting is poorly implemented or if youtube is deliberately switching the setting back.
It seems like a better approach would be to just get rid of those annotations. I don't know how anyone ever thought that was a good idea. But YT should let them link externally. Site's like Patreon are beneficial to everyone involved.
Getting rid of them entirely would get rid of an easy and much needed way for the uploader to add corrections and other additions after the fact.
I do see videos where the annotations are rather annoying, but I don't think it's so often that it has been a terrible problem overall, and I have a suspicion that on those videos the annotations have not been the only annoying aspect.
Edit: I just saw further down that annotations are actually deprecated, and now I really wonder how people can add corrections to videos? Does that mean I have to read the description of every video I watch?
