Okay, that seem to work.
But I'm not able to get this work:
(add-hook 'org-after-sorting-entries-or-items-hook
(lambda() (org-cycle-hide-drawers 'children)))
After running the sort, all the LOGBOOK draws are still open.
I'm also thinking: even if this closes the logbook draws, all the nodes will be unfolded. But my node tree is quite large. Is it be possible to refold all the nodes after n-levels?
So let's say I have:
* Level 1
** Level 2
*** Level 3
If I move the point to Level 1 and sort, I'd like it fold all Level 2 items, but leave Level 1 unfolded.
