Problems with the volume bar in videos

Hello, I have 2 feature requests due to these problems:

1- the picture in picture button is in the way of the volume control bar, could you please move it to another place? (like on the left side)

2- the volume control bar doesn't seem to scale properly.
One expects each X% to increase the volume by X% like in common players, but instead the changes below 50% are minimal and those above 75% are extreme. Please use a linear scale.
