(Brion Vibber vibber@aludra.usc.edu):
Another odd option is "show hoverbox over wiki links". IIRC, unchecking this will remove the 'title' attributes from the <a href>s. I don't know if that's something that can be done by CSS... I also don't know if anyone uses or wants the option.
I see no reason not to remove that option (and always have the hover box, not always remove it).
There's also the stub detector. Difficult to CSSize that, as the threshold is user-selected. Simplest to disable caching for the rare users who use it.
What does that do again?
