Property Inheritance, I am confused about the > system wide and file wide properties? d) the inheritance rules of these levels - In the manual it says it is off (7.4 Property Inheritance): ,---- | Org mode does not turn this on by default, because it can slow down | property searches significantly and is often not needed. However, if | you find inheritance useful, you can turn it on by setting the variable | `org-use-property-inheritance'. `---- But based on my experience it is on? Also in the examples it is on? Especially the inheritance with the combination of the + is confusing to me. If inheritance is on, the + should add an argument to the header-args property, while without the +, it should overwrite the inherited property?
