first off, I have to let you know.. I've been a devoted 2.5 user forever.. the only reason I had 3.x installed on my machine at all was because they had a really nice import ability.. which is what I'm putting on my wish list..
it was nice in the fact that you could not only specify which fields were imported, but you could specify what their corresponding db field was.. (i.e. you didn't have to have your imported data structured the same way as your db table structure).
so.. that's my wish :)
