Am I the only one who thinks TIDAL playlists that you have created should also show up in the Roon TIDAL interface or maybe have a setting to filter out all the non-TIDAL playlists through Roon?
If this is a feature request, you should consider posting it again to that area.
If you are trying to identify a group of like-thinking users, Roon has reported that multiple requests of the same feature do not have any impact on their decision making. So getting, say, 35 users to agree with your idea won’t be productive.
A suggested work around…
You could put an indicator in your playlist naming for all Tidal playlists, maybe (T) at the end or TDL and then filter on that in the Playlist list in Roon.
