Project Related Task

This module adds a way to connect tasks that are related but are not parent and child. On the task form you get a new "Related Tasks" tab, next to the sub-tasks area, where you can pick other tasks to link.

• The list inside the tab is editable directly, so you can add, remove and reorder related tasks without leaving the form. You can also open a related task from the list.
• The list shows useful columns such as priority, status, task name, project, milestone, customer, assignees, deadline, next activity, rating, tags and stage. Finished or cancelled tasks appear greyed out.
• When you add a task from the tab, some values are pre-filled from the current task: the same project, customer, assignees and milestone (when milestones are enabled), and the task is not shown in the project by default.
• A hidden search filter called "Same customer" is applied automatically when searching for tasks to link, so by default you see tasks of the same customer.
• The link works both ways: if task A is related to task B, then task B also shows task A as related. The module keeps both directions in sync automatically.

The module only touches the task model (project.task) and the task form and search views. It does not add menus, reports, emails or scheduled actions.
