Feature summary (what you would like to be able to do and where):
It would be nice for DiscussionTools to automatically search for sections on discussion pages that have since been archived, similar to https://en.wikipedia.org/wiki/User:SD0001/find-archived-section.

Use case(s) (list the steps that you performed to discover that problem, and describe the actual underlying problem which you want to solve. Do not describe only a solution):
Links often are made to sections on discussion boards, talk pages, etc, but those sections are archived and hard to find.

Benefits (why should this be implemented?):
Helps with usability and prevents link rot.
