I'm looking forward to this feature! I hope this will allow for simple
file system level synchronisation (without touching any database) -
which even with metadata embedded in image files is not currently
possible in digiKam (see https://bugs.kde.org/show_bug.cgi?id=173632
"Transparent update of picture content and metadata after file update
and on software start").

This should also speed up writing metadata "to files", if just small
XMP sidecar files are modified, instead of picture files (which digiKam
then apparently automatically rereads). That would render the wish
"Metadata delay write option"
(https://bugs.kde.org/show_bug.cgi?id=218730) pretty much
superfluous (so that maybe it could be closed).

I still have the problem of two operating systems on one computer
reading the same pictures, sometimes with different versions of
digiKam - and not being able to simply use digiKam on both systems.
Just symlinking the SQLite database first seemed to work, but
eventually I could no longer write the database on one system, if I
remember correctly. Even the new MySQL support is not necessarily a
solution for this problem, because I don't want to always switch on a
second computer as an external MySQL server just to be able to use
digiKam.

But XMP sidecar files COULD finally solve this, if there was an option
to automatically update the database whenever XMP files changed.
Gilles answer to "Synchronize digikam databases between computers" (on
Saturday, 6th of November) suggests this could be the case. :-)
