Comment 8 for bug 1321841

I thought of a simpler way to implement something like this that would not require a total revamp of the library GUI. There could be a way to specify a hierarchy of sorting the library columns. The simplest (and I presume easiest to implement) and least flexible way would be to sort left-to-right. For example, if I put the columns, from left to right, Artist, Album, disc # (see Bug 1411120), Track #, Title, then Mixxx would first sort by artist, then within each artist, sort by album, then within each album, sort by disc #, then within each disc #, sort by track #. Alternatively, there could be a little editor window to specify the sort priority of columns so they could be sorted and displayed in any arbitrary order.
