Downloaded a trial of NoteMind.
It enables you to display your collected documents as a mind map, and modify them in any way you like.
This might be of some interest for a future version of Scrivener. The mind map function is quite appealing. NoteMind automatically creates mind maps of your folder tree. It is a bit like the Binder in Scrivener - on steroids. Mind maps can be edited with external layout applications, and comments and annotations can be added.
Worth a look. One for the wish list.
EDIT: Italicised the word ‘might’.
