Adding tasks and sections to Goals

Just to add what has been said above, after πŸ₯… Introducing OKR goal types and org-wide goal templates we have now a very nice progression from organization goals to layers of subgoals to more narrowed project and individual key results. Meanwhile, Milestones are already recognized by goals, as you can set the % of completion based on the milestones completed in a project. The only piece missing to glue the goals levels with the tasks level is to let milestones contribute directly to a goal.

In technical terms, you already have the goal selection that allows to define the parent goal of a goal. Milestones could have the same goal selector.
