This is a similar request to this question, (which suggests a feature which would be just as useful).
When questions/answers are linked to, it appears on the right side-bar under a title 'linked'. I would quite like to see another section (or perhaps merged with the 'linked' section) which includes Codex pages that are linked to as well.
This would provide a quick reference to related Codex pages and, I think, would be useful to those with similar questions as well the OP. (And it wouldn't prove too difficult to implement :D.)
