 - `weeklyResetDay` suit les jours JavaScript : `0` dimanche, `1` lundi, ..., `6` samedi.
 - `resetTime` est global à l'outil et vaut `HH:MM`.
+- `hideCompleted` masque les tâches effectuées à l'affichage, ainsi que les catégories dont toutes les tâches sont effectuées.
 - `weeklyResetDay` sur une tâche hebdo surcharge le jour global.
 - `category` sur une tâche racine est facultatif. Les tâches enfants héritent de la catégorie effective de leur parent et ne stockent pas de catégorie propre.
 - Les tâches catégorisées sont regroupées par catégorie au niveau racine.
 - `categoryOrder` stocke l'ordre d'affichage des catégories utilisées. Les catégories absentes des tâches sont retirées à la normalisation.
+- `collapsedCategories` stocke les noms des catégories repliées.
 - `relations` stocke les parents directionnels. `fromTaskId` désigne la tâche enfant, `toTaskId` son parent.
 - une tâche ne conserve qu'un seul parent.
 - `prerequisite: true` marque aussi ce parent comme pré requis.
