Issue: Option to show list of synonyms on page to e.g. admins/editors

We have quite many pages that have multiple synonyms.

In our infobox we have usually those listed as "other names"

Some of the editors have forgotten to add the synonyms for the pages..

Now to check this, we have to "manage synonyms" to get a list of the synonyms..

We would like an option in e.g. aesthetics like "show synonyms next to title for logged in users" (or similar).

With this enabled, in the Title/Header of the page, it would show something like (Synonyms: foo, bar, baz)

If this is possible already with a template modification, please tell me how
