I put up a new Mac version of JW Space Systems (free) on my download
page. It restores the group boxes on the dialog and is "part aware".
Right now being part aware doesn't change anything about how it behaves,
but it might in a future version.

(You can run it against parts now, btw. It works exactly as one would
expect it to. You just have to invoke it score view, then change to the
part you want to run it against.)
