The tooltip for "Indirect" suggests that it is used for displaying the content of the page (direct+indirect members).
But it is also used when running Recompute action menu from the members.
If the Indirect is checked, the tasks runs over direct+indirect, otherwise only direct members.
But this is not very intuitive. And the checkbox is "too far" from the Recompute action in the menu.
Suggestion 1: rephrase the tooltip from "show" to "work with"?
Suggestion 2: have Recompute direct and Recompute all actions instead of Recompute?
I see the menu of actions has been modified/simplified since 3.8 or 3.7.2 indeed, so I don't want to overcomplicate it again. I'm open to discussion.
