New on the use volumio, but quite happy with it here are some basic improvments I would suggest that make sense for users using QOBUZ plugin.
Add a button close to the search field to select multiple genders of music.
As tools for querying in data bases (I am consultant on finance) be able to sort and filter on the header by Artist/album/track
The button to switch on/off the advanced search is to small when use a mobile, or may be my finger is to big!
Display as property of the album its gender, to facilitate the understanding of how album/track are categorized, this would help for our own searching.
If you need any information, please let me know
