- Ankerwidget staat nu vooraan in de widgetbibliotheek (eerste kaart)
- Nieuw ⚓-item in het ＋-menu: plaatst direct een ankerdiagram op het bord
- Duidelijkere uitleg wat een ankerdiagram is (woordweb voor
woordenschatonderwijs: woorden in samenhang rond een themawoord leren),
in de bibliotheekkaart, de widget-hint en het ＋-menu-label (nl/en)
