[O] "Refiled from..." Notes in LOGBOOK - Feature suggestion

[Stas Vlasov]

Dear org-mode community,

It could be useful to have a note about the place where the entry was refiled 
from. Like so:

* TODO Note on where the entry was refiled from
:LOGBOOK:  
- Refiled on [2016-04-04 Mon 00:57] from ~/emacs-tasks.org::*Tasks%20workflow
- Refiled on [2015-05-15 Fri 13:53] from ~/stuff.org
- State "TODO"       from ""           [2015-05-15 Fri 13:53]
:END:

The current options with org-log-refile in only allow to log time of refile 
event or to prompt for a note.

The problem is that the templates for adding notes in org-log-note-headings do 
not support a proper location placeholder (something like %F used in 
org-capture-templates). It is also explicitly not recommended to change those 
templates.

Maybe add location placeholder or a new refile note template for future 
releases?

Thank you for considering!

Kind regards,
Stas
