reload interval and ignore disabled tracks are useful to everyone, but could go
under plugins like all other plugins.

prefix and suffix, I'm not sure why those need to be there at all.  The find
automatic, library file, and folder setting are for people who seem to believe
that itunes is useful under linux or have somehow found the need/ability to move
where itunes keeps its files.  I have tried over and over to relocate the file
to somewhere useful to me, but itunes always refuses.  you couldmove those
settings, but that will result in a very small but embarassingly vocal minority
screaming even more than they already do ;)

Maybe an important bit of info here is WHY those users felt that they had to
change those settings in the first place.  Does automatic not work well enough?
 Are they just being absurdly anal? which settings are they changing most and
which cause the most harm versus the performance when untouched?

Things are OK now.  Let's see how it goes...
