I have quite a lot of albums with multiple CDs. Most of these CDs actually have their own disc name. Right now I enter this additional "sub album name" in the grouping tag. What would be awesome would be a way to show the individual CD name above the tracks of that CD within musicbee. See https://dl.dropboxusercontent.com/u/104901/mb.JPG
for a mockup.
In the example shown, the first 2 CDs are the original recording, CDs 3 and 4 are a re-recording, but they all belong to the same album. There currently is no place to enter this besides the grouping and there is no way to show it in the UI.
Another example might be (does not exists, just for showing what I mean)
"Disneyland Full Collection" (5 CDs).
CD1 Main Street USA
and so on.
Even though these discs all need to be in the same album, they each have their own disc name and it would be good to be able to show that name somewhere.
