Not with v0.9.1: once a file is copied into your library, it doesn’t get moved around.
People commonly rename directories to include an event name, and I didn’t want to undo that work.
However, perhaps there should be a setting that says “it’s ok to move files found in datestamped directories that don’t match the captured-at time”?
(Feel free to brainstorm nicer/more robust heuristics, and to add this as a feature request so others can vote on it: I’d vote for it!)
