I'll admit that I'm late to the party and can be exceptionally dense at times but I don't understand the $wikify widget. I read the tiddler. It parses some text, renders it and returns it as a variable which is available inside the widget depending on the type selected which defaults to an option which isn't one of the listed choices. What? What? While there are examples in the full Tiddlywiki, there are no examples for the $wikify widget and, as close as I can tell, Tiddlywiki almost never uses it either.
Can someone point me some examples that are simple enough for a borderline moron like me to understand? Jeremy, could we get an example or two in the next version?
