After using the device for a week now, her my wishlist for the music section and other topics:
- Adding more options in the submenu “Artist” such as in iTunes, Clementine, etc.
- Evaluation or implementation of the MP3 tag “Compilation”. At the moment, each piece by an artist appears as a separate album. E.g. in the compilation are 4 songs by “Cravinkel” that appear as 4 albums.
-
Unify or adapt the operating concept of the device and the “Rose Connect” app.
-
Under the item Classification / Artist in “Rose Connect” sort the albums in front of the individual songs and sort the songs under use (and displaying) the track numbers for each Album.
-
Implementation of scroll bars in “Rose Connect”.
-
Implementation of the smb3 protocol.
-
Implementation of the https protocol.
For now 
with best regards,
Frank
