I'm not sure what you mean. I think running whole GUI applications as
root is not the best solution both for security reasons and because it
doesn't integrate priveleged functions where the user needs them,
which is often integrated into the UI of an unpriveleged program

Whether it should be per user is somewhat debatable. But I am pretty
sure it should be stored on the volume because that's essential for
removable media. Storing it in a special file in the root directory or
what have you may still need priveleged access.
