It doesn't fit with mplayer's normal playlist config system, IMHO at
least. What you're looking for is more of an interactive/gui type
feature, and although I agree that it could be useful, I think it
should be implemented at a layer outside of the main mplayer/libaf
code, so that things work as expected in the basic command line case.
