Yes, there is a Folder View along with MQA support for Tidal and much more. I prefer not to keep any of my personal library on my devices but Play Music (soon YT Music) allows uploading 50k songs of your own content as 320k MP3.
It's kind of the shame they have this bitrate limitation. The amount of people that would even take advantage of higher than mp3 quality I would imagine would be a lot less than a fraction of 1% of users , so it seems very arbitrary.
