I'm looking for a plugin that modifies the behavior of the file open function as described:
- If the opened file already exists in one of the playlists, that playlist is made active and file begins to play from that playlist (if the file is in multiple playlists, one should get selected)
- If it's a new file, add it to a new playlist (like the current "Add all incoming files to specific playlist" feature)

Does a plugin that allows the above exist?
