Please help me start up with tags

[MiniMe]

(let's push 8player to the background as plan b)
I think I managed to find a good way of labeling my library (no misused tags anymore), and I think I have 80% set Minimserver to also serve properly.
Sort by quality I did with indexTags: Genre, #AudioQuality:Sorted by quality, this so that MinimServer can help identify formats.
Do you still see improvements for setting the MinimServer even more efficiently?

If then the library is up and running well, I aim to get the Lumin app under control (Linn Kazoo app works similar to (but better than) the Lumin app). Drilling down to the appropriate level indeed gives me playlists I look for without duplicates, but this goes with 6 button presses where I'd expect only 2 button presses. Maybe the Lumin app gives too many icons that I do not need. Also the doubling of items in the playlists is somewhat annoying, is my understanding correct that undoubling of such double items should be done by the control point software?
