There should be a reset all button or just auto-reset when duplicating a project. I duplicated my large project, (15 main tasks, over 5 sub-main tasks and even more sub-sub task). For me to reset the project completely, I have to go into each task, hold Shift and then hit the complete button to incomplete. This would/ did take forever.
Solution: could be that when you duplicate the template/ project it auto reset as incomplete and the date could change to the current year.
This would save time and keep the transition of projects easier.
