it doesn't remember screen ratio or volume boost in next video

As soon the player goes to the next video goes to default the screen ratio and volume settings that can be set with the cog when playing the video.
Is there any way to force it remember the settings? If not, what is the point of a setting that doesn’t remember the status? Even both settings are convenient and I can’t really adjust them in each single video.

The volume and zoom options are currently set on a video by video basis, though we may look at adding global options in a future update.
