21 * @brief User management for Disobedience
f44417cf
RK
22 *
23 * The user management window contains:
24 * - a list of all the users
25 * - an add button
26 * - a delete button
27 * - a user details panel
28 * - an apply button
29 *
30 * When you select a user that user's details are displayed to the right of the
31 * list. Hit the Apply button and any changes are applied.
32 *
33 * When you select 'add' a new empty set of details are displayed to be edited.
34 * Again Apply will commit them.
