I would like a Glossary feature - could be a nice mod. Admin sets KEYWORD on list. (Option for assigned mods too) If that keyword appears in content or title anywhere a tiny icon appears next to it. This is a link to a Page where the word is defined/ decribed. A Glossary page has a link to a meta Glossary Page listing all words in Glossary A-Z in columns. A keyword would need to use a search system so that it covered its root and associated words. So TALKING, TALKED, TALKS would also trigger the Glossary link for TALK.
