Enhance the download options for the player.

It would be good to be able to select bitrate whan downloading a file. I just tried a download with a 20gb 4k hdr movie and when selecting 720p the resulting downloaded file is still 15gb. Would it be possible to add options for bitrate rather than just 1080p 720p and 480p? Also it seems you need to go into settings to see what you have downloaded, could a downloaded library be added or maybe a button on the bottom menu bar to take you to downloads rather than having to go into the settings menu?
