Hi Mike, Skye is right. We have removed the edit button since you can now just turn the autosave off and have the same functionality. We will be adding the ability to edit the Gantt without entering a specific mode as well (coming with 2019.3), so that you can have consistent behaviour with the lists, i.e. when autosave is on, you will be able to edit both the list and the Gantt part but without the ability to undo, when autosave is off, you will be able to edit both parts with the ability to undo.
