One feature that I have found very useful in multiple applications, is the ability to produce code based on your interactive actions taken in the program. For example, Excel does this, you can record a macro while working in the workbook and it will display code based on your actions. This is very useful because sometimes it is difficult to learn exactly how to code certain things.
