Most web pages only support two video sizes: 1. unusably small 2. full screen. Which often means unusably large (27" screen), especially for less-than-HD video

Most web pages only support two video sizes: 1. unusably small 2. full screen. Which often means unusably large (27" screen), especially for less-than-HD videos At least youtube added at some time the cinema mode which allowed the video to occupy the whole window width, that is what I use most of the time. Still, PIP also has the advantage of removing the window decorations, so saving space. Also, they are floating on top of all other windows, which helps, but also occasionally can be annoying.
