How do I use my own folder structure with Shotwell?

view story

http://askubuntu.com – I want to organize my photos as follows: my own folder structure, not date-based not in ~/Pictures automatically detect new photos in my folder structure (including in subfolders) do not create copies of the photos (I need the harddrive space!) Is this possible with Shotwell, and how do I do it? I really don't want Shotwell to move my files around. (HowTos)
