Where is/ Why isn't there an undo option?
I accidentally checked some items on my list which were scheduled to be completed within the next week. These were items that were set with recurring dates. These are now scheduled as overdue from last week when I tried to undo them. I don't know how to fix this, as obviously I want to ensure that I complete these tasks every week, including the one coming.
there is an Undo option at the top of the screen when you delete a certain task. If you check it off, it's being moved to the "Get completed tasks" list at the bottom from where it can be un-checked.
If this task is overdue now and you don't want to complete it again, simply change its due date using the same formula, but add "starting 20. Aug 2012" (for example) at the end of the date format. Please make sure that the starting date is included in the formula so if a task is due "every Monday", it's advised not to start it on Wednesday.
