Dear Tumblr,
Thank you for adding this new “sticky iframe” that repositions itself with JavaScript whenever I scroll the page. Until now, I hadn’t grasped why the blog controls needed to be at the top right of the viewport at all costs, but now I understand that that space is sacred. It belongs to you, and you alone!
Just kidding. I modified two lines of CSS in order to restore the original behavior, leaving the JavaScript that does iframe position checks twice every second functionally inert.
Meanwhile, theme localization is still fundamentally broken, but who has the time to think about all that?
Still, you know, these changes would bother me less, even annoying and unnecessary as they are, were they at least documented somewhere.
