One of my most used Safari Extensions got an update today. I like the feature improvements, but I don't agree on the extensions new location.
By putting it on the side instead of hovering over the page as before it forces you to first read the article, then focus on the extension's button to click it, and then to the right side of the screen where the extension appears.
That's a lot of eye movement for what used to be a single click.
But aside from that nitpicking, it's great.
