I used Logitech Media Server for quite a long time and was in favour of the Echonest/smartmix feature (until Spotify killed it).
At present I only listen to my NAS music collection.
When selecting a title and selecting the Roon Radio option the system will generate songs automatically. Perfect!
The queue list however shows only 1 song i.e. the song which is now playing (and above the songs played). The Roon Radio frame on the right shows the next song to play. This is a very limited design.
Please implement in Roon:
Extend the queue/playlist! Generate automatically a playlist for 1-4 hours. Based on its intelligence Roon already generates a sequence of songs but the system doesnot show it. And the queue page has plenty of room!!
This would give users the opportunity to control a playlist in advance.
To my opinion… a quick win to improve Roon.
