Why are the options in a separate addon?
The SBF options are a full blown graphical thing in their own right, and chew up a fair amount of memory. For most people, setup is something you do once and then leave alone except to tweak once in a while. Given that, it doesn’t make sense for that to be loaded all the time so SBFOptions is a load on demand addon. It only gets loaded when you type /sbf options.
