On the iQuestions page, there is a box on the right entitled "Report a problem".  What about another box with "Suggested improvements"?

It would obviously be great just to get to the point where DS is as good as ACLT it emulates (one day, one day...!).  But how much better if it could go beyond AC?  And that shouldn't be hard because there is a lot ACLT could do better.  If DS aspires to being an Autodesk killer, it needs such an aspiration.
