The order of the three is fixed. It goes from settings for
all projects, over the shared options of one project, to the user
specific options of one project.
Theoretically there could be three checkboxes to hide and show the
three storages, but IMO that is more confusing.

The order does matter and putting an option in the wrong storage
can have serious effects. For example if you accidentally put a session
option into the project, you will break your team mates code.
If you accidentally put a project option into the IDE you might break
your other projects.
IMO the storage and scope of an option must be made very clear to
avoid such accidents.

I will add a todo to let the IDE warn, when you compile a project that
changes the output directory of packages.
