strange behaviour obligated checkbox bool
Try editToDoList. In editSharedList, but perhaps also for the other editors, an obligated bool results in a checkbox. However, it is impossible to tell whether an unchecked box is forgotten, or simply marked as unchecked on purpose. Currently one first has to check the box, and then uncheck it. Otherwise an unmarked checkbox is not accepted.
Hence the default way to treat an obligatory checkbox of type Bool should be the same as an maybe bool.
