I don't know how hard either of these would be, but here are thoughts on a couple of enhancements:
1. support the != construct. I don't believe PPL can use this yet, but it would be cool.
2. support a default directory in the GetFile & PutFile functions. It would be really neat to either pass in the application's working directory or the last directory that was surfed to for the next time the user chooses to open / save a file.
Neither of these are really important, but they would be nice if they weren't too hard to do.
