Improving Task Discipline: No Assignee or Due Date on Tasks

Here is an existing feedback request thread I recommend to upvote:

Set Due Date as Required field

My employees sometimes forget due dates on our tasks and subtasks. For our system to work properly, those dates have to be filled it. How can we set the due dates as required fields, so without them you can’t leave the page???

Now in case you require the same for a custom field selection you can set something up via rules similar to what I explained here.
The example I posted was for no task completion before updating a specific field but basically similar can be set up for task creation via comments being added or tasks moved back to a section if conditions are not met.
