I like to create boards of future projects (as tasks), and as the project is assigned, create the actual project from the task. This is helpful because my team can look at the big picture, and assign each task as a project to developers.
However, when you convert the task to a project, changes made to one are not reflected on the other, and the task is marked as complete for some reason. Instead if the task was linked to its associated project, changes made to the project by developers would be reflected in my task and vice versa.
I’m sure this would be a very useful tool for many.
