Use field descriptions instead of using field names

[elcapo]

When listing fields in filters, or parameters, we are always showing its names. A list of fields, for us, could be something like: id, first_name, email and custom_1. If, instead of showing field names we used field descriptions, the list would have been: Internal Contact ID, First Name, Primary Email and Document Number Contact::Legal Info.

Note: An example on how can we obtain a list of field descriptions can be found at civicrm/api/doc at any CiviCRM instance.
