how can I copy a task and its associated sub-tasks?
You aren't able to do this. You can right click on a project, and use the Export feature which will export all tasks under that project.
1) right click on tasks does not give me anything
2) Exporting is way too techie and counter-intuitive. I have never been able to make it work. I am not a programmer
Sorry for the misunderstanding. You need to actually head into the Project, top right corner, there is button, then choose Export. This then downloads to a TXT file, which you can then follow the same steps and import.
Why is it not possible just to make a copy of a task? There are lost of reasons why you would do this one example is a task is
Do A and B. Later you want to keep the priority,tags and project the same but split into task A and Task B with different dates.
+1 for a simple way to copy/paste tasks
Suppose there are six important steps to a task that I will need to do a few times next year, I'm not sure when yet. I've figured out these steps, and set them up as a task with the appropriate subtasks. Now I want a mechanism to save this, so that it will easily be available at some unknown time in the future.
It appears that if I Export this task with its subtasks, I'll get a text file, which I will need to maintain on my own. I'll need to create a folder for it, put it in that folder, and remember where I put that folder. When I need it, several months from now, I'll have to go find that folder, and Import it from there.
That's not an impossible task. But what I think what people are saying is that it would be much easier to be able to "copy" a given task and its subtasks, and paste it in place when I need it next February or whenever.
