Some problems with Crosswords

Here are some problems I have with extension community crosswords:

1) To Publish/unpublish crosswords has no effect in backend - they are always published.

2) Is it possible to preview the crosswords before publish them to see if keywords are well connected or not?

3) The "Solve Question"-button does not make sense. It solves the keyword directly, no matter what you typed in.

Thanks in advance
