1. If I understand your question, and Bimlas' question, then the answer is a qualified "yes". Under some circumstances it allows flows that are otherwise impossible. For instance, if you have a set of tags and want use a count of each one as the input to another macro, perhaps for graphing purposes, you immediately encounter a problem: the count operator generates exactly one output. The only way to get an output like "5 12 16" is take a series of list outputs and combine them via wikify. 2. You can't use the output of a widget as the input to the attribute of another widget. That is, you can't do something like: <$widget name=<$otherwidget attrib="stuff"/>/> Widgets are like HTML tags, and you can't pass a HTML tag to the attribute of another HTML tag. Also, a filter wants a single string with no line breaks: "[tag[stuff]has[field]]" but the list widget outputs everything with line breaks. OK, I "think" it outputs with linebreaks. It's hard to tell because if you let the browser render the output without explicitly putting in <br/> the browser renderer compresses out the line spaces.In any event, if you let Wikify do the rendering, any excess linefeeds will be removed before conversion to a string, just like the browser renderer does.
