Library management for large collections

I listen to classical music and other genres. I do have have my file system tree split in “classical” and “others” folders.
I created 2 smart lists and it works reasonably well, but I miss the option to change the listing orders in the smart lists.
It would be great to be either able to add some flexibility to the way smart lists can be ordered, or even better to be able to create multipe libraries.
Also some of the titles ( both album and song) are at times pretty long (esp. for classical music) and cannot be entirely read in the remote (android): it would be great to have soem sort of multilines display or horizontal scrolling if only one line is visible.
thank you
