What do you think about just leaving Unattached Items visible? I had essentially the same problem in jEmplode and decided that it may actually be helpful in some instances to have that playlist visible so I decided to leave it. One example is that jEmplode shows modified nodes colorized Red -- when you sync to an Empeg that has database errors (aborted sync or whatever), it's really unclear what got "fixed" if something is moved to Unattached. By leaving it in, Unattached gets marked Red to show that it has "modified" (in this case, the nodes were moved to Unattached to repair the problems).

Just my two cents
