It seems WikiEditor has recently undergone a change (at least that’s how it feels on Wiktionary.fr). Under "Special Characters", on Wiktionary.fr we used to have two small sets of characters for French and French API. Now "Special Characters" shows several scripts (Latin, Greek, Arabic, Tamil, etc.) and our character subsets are drowned in the Latin and API listings. How can one add customised subsets to WikiEditor (like one can with Edittools)?
