Some time ago I have reduced the heights of the largest tables in my database model to minimize its size. That way, I have scaled several tables. Many columns in these tables where hidden. Unfortunately, there are no icons within the down-scaled tables indicating that these tables have more columns than are displayed. In my opinion, this is a fundamental feature to know which tables have additional, hidden content. In all other applications, there are relevant icons (usually in the right bottom corner) indicating that the object has more content inside it. It's very important to have such information available, especially when you're working an a huge database model for a long time and it's very likely that you forget which tables were vertically scaled.
