"Tool" is where you manage your study tool profiles and configurations.
A "Tool Profile" is a collection of options related to the study tools such as the "Flash" tool. In it you can configure things like the languages used, the study item selection algorithm, and even how many study card sides there are. It also stores the tool configurations, described next. You can create multiple tool profiles.
A "Tool Configuration" specifies what is displayed in the study cards. You can create multiple tool configurations within a profile. A number of tool configurations are created by default when a new tool profile is created.
A default tool profile and set of tool configurations is created for you the first time you use a study tool. You can set up a default template used to create your default tool profile. Your tool profiles are keyed to your current account profile.
