First I wish to thank you all who contribute to Volumio. I have used Volumio for at least 2 years as my main musicplayer(s). The latest version is awesome! Thanks!
I use two RPI 2 using the same NAS (Multiroom) and a feature I miss is that if I make one playlist on one of the devices I would like it to turn up on the second. I remember I have manually copied the playlists at some point, but that was a bit too cumbersome.
I would would like to playlists to be mirrored, but another possibility is to have one device as the main/primary and the second as a copied version.
