The big advantage of weekly goals is being able to break down a larger goal into smaller tasks.
But if 1 have more than 1 weekly objective and assign several small tasks to the goals, I can't see at a glance in the weekly view to which goal the task belongs. This makes it overwhelming, as the weekly view is then full of tasks that have the same weekly objective icon.
A solution could be: Assign a color to each objective. All tasks associated with this objective will automatically get the same color.
