I think the instructions here should apply, somewhat.
The options for changing these are in the Preferences menu>Panels UI>Library Filter
ARTIST
$if3(%album artist sort%,$meta(album artist),%artist sort%,%artist%)
$ifequal($get(isSingle),1,! Singles,%date% - %album%)
Disc %discnumber% - %tracknumber% - %title%
these are two ways of displaying the stuff. each line is a different tier in the category: under Artist, it checks for artist sort tags, then date/albums then disc/track/titles
in my library filter settings code:
$if($stricmp(%criteria%,%album artist sort%),
%album artist%,
$if($stricmp(%criteria%,%artist sort%),
%artist%,
$if($stricmp(%criteria%,%album sort%),
%album%,
$if($stricmp(%criteria%,%title sort%),
%title%,
$if($stricmp(%criteria%,Disc %discnumber% - %tracknumber% - %title%),
$ifgreater(%totaldiscs%,1,Disc %discnumber% - ,)%tracknumber% - %title%,
$if($stricmp(%criteria%,%date% - %album%),
$get(datedisplay) - %album%,
%criteria%
)
)
)
)
)
)
Which basically goes down the hierarchy of if statements checking for a match, replacing sort tags with actual info tags. If you only want to replace "%date% %album%" with "%album%" then you'd just use
$if($stricmp(%criteria%,%date% %album%),
%album%
,
%criteria%
)
There's also Playlist Tree, which can organize and present things just about any way you please, but it's got something of a learning curve (and it may not work perfectly with the latest beta).
Also, it's no longer supported by CWB
