This new update screws with my OCD and broke how I use Youtube. Other people may like the new fancy look or filters but for me the update has no upsides. I miss the toolbar, which was great in or out of the comments section and didn't mess with the video; plus I liked the customization.

Replacing the toolbar with player controls means that to adjust playback speed with just the mouse I need to scroll over the video area and the popup controls cover part of the video. Ctrl+mousewheel isn't as convenient, nor is mapping keys to ditch the mouse. I adjust playback speed A LOT during videos so normal use now means I'll have lots of visual distractions. This is probably a good chance for me to use far less Youtube, since I notice I was relying on the previous version a lot.
