detect moved files

[f.a.b white]

hey list!

i'm using "super flexible file synchronizers" (sffs) with windows for
years and now try to find something similar on linux.

rsync has quite the featureset that i like (still, i miss the
graphical interactivity, and unison doesn't quite match it), but one
feature is completely missing: detecting moved files.
from sffs' feature description: "Detects Moved Files. If you
reorganized your folders by moving files to different locations, Super
Flexible File Synchronizer will detect this and quickly perform the
same moves, for example, on your laptop. No extraneous copying!" - so
when you move files within the source, they won't get deleted and
copied again on the dest, but just moved within the dest.

is this feature planned (i didn't see it on the todo list at least)?

greetings,
fabb
