Hello,

There are many problems that can be represented by a tree, and the org mode
refile UI is actually a good UI to refactor a tree of headings. My idea is
to transform my hierarchical data into an org-mode file, and use the refile
UI to apply changes to the tree. If the refile actions are recorded, then I
can process externally this record of tree changes and get them reviewed
and later applied.

Do you see a good way to record a "refile session"?
Maybe I can just turn some logging before the refile session and parse the
log?

One example of such a tree I need to refactor is a set of directories and
markdown files making up a wiki.

Regards,
