Just a note for other s9y users who (like me) are not XML experts, and encounter XML-based plugins...
When using plugins like "Link List" where you need to code in XML, remember to be mindful of XML reserved characters. I forgot that ampersands cannot be used with XML without escaping it some way, and it kept messing up my sidebar links.
It is not just an XML issue... you should never really use the ampersand by itself anywhere, such as in entries, links, etc. & is always the way to go.
