1. Clear deleted tasks: The idea is to be able to go back in time and see what was done. Do you have too many tasks? Is that why you want to remove them?

2. A goal stays in the sidebar as a reminder of your goals of the week. You can drag it into your week and it becomes a task too, but sometimes it takes several smae tasks to finish the goal (example: Go to gym x3 as a goal would result in 3 tasks). This is the reasoning behind it.
