I know that, and I like it, especially in JRemote, where I can add all kinds of levels that are relevant for some albums, but not at all for others.
The problem is that I have a display field that for 99 out of 100 of the artists on the main, first level is identical within each grouping. But for that 1 out of a 100 I have, say, 1 out of 20 that is blank. In that scenario Theater View displays the 1 blank one. Why?
In J remote it crashes.
