It would be good to have the flexibility that you describe Lisa.
I have also found that after a rescan of a usb library, the Wiim Ultra duplicates some albums. This means that, in the better case, two albums appear in the list, or, in the worst case, one album appears but each track appears twice. It would be great if there were flexibility to delete the unwanted 'second' album entry. I guess this is not possible becuse of the Wiim rrading the usb as a server. Right now, to remove the unwanted second entry, I have to take everything down, go back to the database, on a PC, delete the file, then rescan the disk on the Ultra. Very clunky and time-consuming.
I notice too that album artwork does appear after ripping a CD using Windows player 11. The Wiim Ultra also refuses to add a pdf file of an album cover. Not much point in having a screen capable of displaying artwork if the machine does not pick it up.
I'm sure these are all 'first-world' problems but frustrating nevertheless. Overall I'm happy with the Ultra.
