I have created a project and set the Gantt (timeline) view to the correct size (zoom out) and only the high-level tasks were visible (ie, shrunk the child tasks).

I then go to save my project and close it.  When I re-open the project, the default zoom is used and all tasks (both parent and children) are visible/collapsed out again.

Is there a way to save the project such that the Gantt view that is set is kept as the new default for that project?
