One feature I’ve always missed is support of Rating of Albums and also rating of Songs, which could be done from the “info” screens that already exists for Albums and for Songs respectively.
I’ve noticed Yatse already supports rating of currently-played songs but this is a bit awkward in general, if you want to rate hundreds of songs, you need to play each of them in order to be able to rate them. Also, in my use case I rate albums too, so I can sort albums by rating.
Kodi’s web interface (chorus2) supports rating both Albums and Songs from the lists, however the UI for this is a bit awkward to use in smartphone. It would be fantastic to have this in yatse.
