Mosaic - best albums function

Hi,

should be nice to have the ability to tag a folder, an album, an artist, …
something as a like which can appears as an icon on the detailed view at least
should be fine to tag directly from the list through the … access
something like a playlist, but at the album level.
with existing mosaic i can add a full album to a prefered playlist, but i see as a track list which is difficult to browse efficiently with a great number of tag
of course having multiple tags should be best of bread … but one should be fine

regards
Pierre
