The reason I actually hate YouTube annotations are that they are annoying big fat boxes of video publishers who want me to click me somewhere to go somewhere else and but I want to watch and enjoy videos without distractions. From my point of view annotations are good for publishers but bad for the actually consumers. People are using them in the worst possible ways I cant stand like having big fat back and forth links on the videos all the freaking time. Or “click here watch this” on the actual beginning on videos. I mean I am not opening a video just to go to another one. I want to watch videos and not have this things on my face. If there are links people can put them into the description and I can use them to my liking if and when I want.
There are exceptions when people do this previews at the end of videos and you can click them via annotations, they can actually be helpful for me to. If youtube would have this feature to show them just for the last 5 secs of vids i would use them. And stop at the last frame for that matter ??
There you have it, this is why. So you’ll need this quick edit for now, not that hard to edit updates are not that often.
Maybe a better way I guess you could use JavaScript to modify the iframe src url from a external file so you would have to redo it every update.
Also I am having this Idea of custom parameters for all providers but I am not sure if/when I will find the time to code this. [hint]I am taking pull requests in github[/hint]
