Rebuild w/Logging is only used for support purposes, so I believe I chose to leave that off.
(w/ is a shorthand for 'with'). Haven't had a report about database rebuild problems
in a while, usually someone has an mp3 with really long tag data and it doesn't fit in my database.
The other three only show up if the associated option is turned on.
iTunes support is a global option, organization is in configuration / organization
and writing audio file tags is in configuration / options / audio files.
You could create a second installation of BallroomDJ into a different folder
if you want to test changing the options -- I wouldn't want you to create problems
with your standard installation.
