At the moment, the project homepage isn't as useful as it could be. Some suggestions for improvements include:

Project structure view
See an outline of your chapters and sub-chapters without having to navigate to the planning page.

Custom goals
Set project-specific goals that can include anything from deadlines to word counts and custom timeframes.

A project task list
Choose from preset task lists based on your writing and/or publishing goals, or create your own task lists based on what you'd like to achieve which you can check once you've completed.
