When the editor is in French :
1) "creator/author" should be written "créateur·ice" but I guess the font doesn't have the middle point · (in my opinion you can just write "créateurice", it's much simple, but I guess it could be confusing to some people)
2) "Go back to level list"/"Retour à la liste des niveaux" is written outside the box. I guess it could be shortened to "Liste des niveaux" ?
