I'd like it split into three click-to-sort columns, form, field name, data type
This would especially be handy when doing maintenance on "other people's applications"/applications that have unpredictable data-types.
For instance:
Person first_name (String)
Person last_name (String)
Person date_of_birth (Date)
Person debt (Number)
Or a bad example:
Person pcode (Number)
Person dob (String)
Person debt (String)
Person field_1 (String)
Car field_1_1 (Number)
Car
