I'll put it on my list of things to do.

The serial interface isn't that hard to implement, but I just need to finish up a few projects here before working on Palantir some more. I've still got my original goasl of re-arranging playlist items and selcting which action to take (insert/append/replace), but I'll do the serial interface when I do the rest. Since I'm making one menu it won't be hard to add another option to it.
