See /docs/common-htmlawed-settings for common settings.

This is a great API that many other modules use. Here is the info from the project page that summarizes it well: "The Field API in Drupal core lacks the ability for other modules to easily alter field formatter settings forms and the formatter summaries. This module is a small API provider for other modules since it's too late to get the hooks into core..."

The description at Drupal.org describes this module the best:"This module creates separate "Edit account" and "Edit profile" tabs for each user, with custom user fields configured under "Edit profile."
