I am trying to move
*** b3 from this state:
* a1 ** a2 * b1 ** b2 *** b3
to this state:
* a1 ** a2 *** b3 * b1 ** b2
But I can't do that with
(org-refile), because it allows me to only target
** a2 is NOT an option, only
* a1 from the a-branch is available to select from the minibuffer menu,
** a2 subheader is NOT available for selection.
Any idea how to org-refile b3 under a2?
