hello, I'm not sure if this is a feature, or I'm missing something, but if I set up an outline like this:
* 2017 :PROPERTIES: :VISIBILITY: folded :END: ** december :PROPERTIES: :VISIBILITY: folded :END: *** 31 *** 30 ** november :PROPERTIES: :VISIBILITY: folded :END: .... the headlines underneath 2016 don't get folded. If I manually delete the visibility property of the months, it gets folded. Reason for this setup is that after each done year, I'd like to hide all its children without manually going through each month and deleting the property.
