Hi,
You can set your own tags on product and those sort/filter by those tags. For example, I put a LIVE tag on all Live music I have in Roon which allows me to filter to only live music in a click. This can be done for any category you want to create for yourself. Also, you can sort by resolution, Go to Albums, hit Focus, sort by Format.
The “scroll vertically” is already being discussed and if you want to add your voice I suggest you enter into that discussion.Vertical scrolling [On Roadmap]
Many things can be found, including How To’s by searching in the forums. As of now, there is no compendium of How To’s.
