This was the narrow sidebar vs the full one on osx
Now you can only disable it and get the top bar only:
@krischik I also liked the wide version because the vertical arrangement of the button is strange for me.
Hope it comes back , or we can make a feature request to out the setting back, maybe they forgot it
You all are wrong
It'd be better if it were an option for the browser to render "plain show" as static and the full view will be on hover. If you're talking about like "GIF tables" of sorts...
Krischik, how did you do the superscript?
