First let me get the request out of the way; in the latest release you removed the 3-dot menu associated with disc containers generated by MinimServer and presented in the form ">> Disc <n>", but discs can also have labels (from the discsubtitle tag), can these be removed too? Example can be seen in AlbumShowMetadata.jpg
By customising the comment tag in MinimServer I'm able to generate html that's passed to BubbleUPnP in the <dc:description> tag. If I click on the 3-dot menu in an album's header section and select Show Metadata, the hyperlinks are presented correctly, but if I click on the 3-dot menu next to a track the icons - used to link to AllMusic - are missing. I've looked at the DIDL and I can't see any difference between the two. Images AlbumShowMetadata.jpg and TrackShowMetadata.jpg.
I'll send you a debug log shortly for the artwork issue, and some logging from upplay that may help with the html issue.
Thanks
