There is a swing "hack" of suggesting an initial filename for a file save dialog by calling
(.setSelectedFile FileDialog (file "blub"))
I think a :selected-file option for file-chooser would be convenient for this.
Also worth thinking of a better name like :suggest-name maybe
Sounds totally reasonable to me. I'm not sure when I can get to it, but patches welcome :)
