It would be nice if there was an ability to have tasks show up in certain colors if they met certain conditions, especially in the Table view. The conditions and color choices would be configurable.
For example, milestones could be in a blue italic font when viewing in the Table view.
When a task is marked complete, its row in the Table view is shaded green.
Parent tasks could be bolded.
Conditional formatting could visually call out certain project aspects that the team needs to focus on as shown below in a mock up I put together.
