Official moOde 7.4.y support thread

Big benefit to me is central hierarchy and playlists for all devices and control points.

This made me think of a possibility.  One thing that did change from 6.x to 7.x was the way in which the MPD library was indexed.  If I'm not mistaken, the UPnP browser function does not work like a classic control point, but rather presents the UPnP source as folder to be indexed.  MPD then stores the location and file details and handles all the queue management from it's own index.  Now a DLNA hierarchy can have the same track from the same location presented in Albums, then again in Artist, then again in Genres.  Usually one must navigate right down to the Album "folder" in the UPnP browser and mount there so that MPD sees an Album by Artist structure that it is expecting.
So assuming that @Jedrek is mounting at a point before "Album" in his presented DLNA structure, the issue could be that since v7 of moOde the MDP index can no longer tell between a track in Album and the same track in Artist, gets confused and abandons the index.  If my conjectures here are correct, then changing the Album Key to Folder in the Library (Advanced) section of the preferences menu might resolve things.  There would likely be a lot of duplication in the Library and Tag views, but I suspect Folder view would be what you'd want in this use case anyway.

I would have tested it but I don't have time to rescan my library a few times this morning, hopefully my musing make sense and @Jedrek can have a go and see if it works.
