Hello 
there are some features that could be added to improve project view and be useful:
List of sub-projects (an example in screenshot, but there may be better graphical solutions)
Ability to view tasks from sub-projects from parents (with the option to choose the level)
Display the parents of the current project (like breadcrumbs)
I think they are aesthetic suggestions capable of improving usability and effectiveness.
Note:
the screenshots are just to explain, not to suggest how to implement them
Best Regards,
Massimiliano
