As for the original question of this thread: Yes I think SMS would profit from a litttle more openness about the way they are heading and feedback to those who contributed.

It is tale telling they do not have an own forum where users can drop their ideas and opinions. This is Renderosity. Are they reading?

I like the approach of for example MarvelousDesigner. They have a 'feature request' forum where threads are decorated with posts from developers saying 'ETA of this feature is October 2011', or 'implemented in version 2.9.3'. A response 'this is not going to happen' I have not seen, but that could be a cultural thing.
