+- Ajouter une tâche
+- Renommer la tâche
+- Terminer une tâche
+- Supprimer une tâche
+- Saisir la note d'une tâche
+- Ajouter des sous tâches à une autre
+- Renommer des sous tâches d'une autre
+- Terminer des sous tâches d'une autre
+- Supprimer des sous tâches d'une autre
+
+- J'aimerai "tagger" une tâche comme "asynchrone/bloquante" (où je dois attendre la fin, genre un build jenkins) et donc être notifié toutes les 5mins d'aller vérifier si la tâche est terminée. 
+- Quand je termine une sous tâche, je veux qu'elle soit archivée pour pouvoir la consulter à postériori
+- J'aimerai définir un e API sur laquelle je pourrais sauverader mes tâches, à la manière de git
