How can I increase the identation in org-mode lists?

Question

I would like to use more than two spaces for list indentation. I've had a look at the documentation, but I couldn't find a variable for that. Instead of this:

 - First
   - First
   - Second
 - Second
   - First

… I would prefer this indentation for better legibility of the indentation levels:

 - First
     - First
     - Second
 - Second
     - First

Answer 1

I've overlooked the variable that controls it: org-list-indent-offset. I've added this now to my configuration:

(setq-default org-list-indent-offset 4)
