There are a couple of potential enhancements relating to the Computed Field Module in the datalab:
A computed field cannot be used as a column for a second computed field.
Add the ability to perform operations (Add/Subtract/Multiply/Divide) with user-defined constants. (Currently, operations can only be performed between two existing columns in the datalab).
Add aggregation function for checkbox-group form fields (eg, determine the total number of classes a student attended from an Attendance checkbox-group form field)
