Good question, I also would like to know the experience of others.
My flow (which I would like to improve):
- open Graph
- find orphan page and open it
- add property
tags::to page or delete a page - repeat
Unfortunatly it is not possible to have graph on main screen and open page on sidebar with Shift+left click
Maybe it is possible to create a query to show all orphan pages. It would be better.
