Is it possible to 'un-complete' a task?
I marked the wrong task as complete, and it has a bunch of sub-tasks that have notes. Is it possible to un-complete them or do I have to create them again?
yes, it's possible to un-complete any task unless you click on the "Delete completed" link at the bottom of your task list.
You can access your completed tasks by going into a project, scrolling down to the bottom of your task list, clicking on the "Show completed tasks" link and simply un-checking a task.
See how it's done in this short video:
Also, even if you delete a task permanently using the "Delete completed" list, you can still access its notes in the "## Completed" completion history in the upper-right corner.
Hm. Yes, I had a feeling I remembered it being that easy. In which case my *actual* problem is that the tick boxes aren't showing in Chrome. Is there an issue at the moment?
