The admin homescreen differs slightly, depending on user permissions. Restricted users see a restricted homepage, whilst admin users see a more detailed screen. This page details a few options available to admin users.

Graph - The graph details sales for tangible goods and downloads.
Filters - Filter by current day, week, month or year.
Sales Totals - Based on filter selection
Quick Links - Quickly jump to certain pages in the admin area. Links can be added to, see below.

The default view is the current day. To change this to the current week, month, or year edit the 'admin/control/defined.inc.php' file and the following: define('ADMIN_HOME_DEFAULT_SALES_VIEW', 'today');

To edit the quick links, add/remove links in the following unencoded file: admin/templates/system/main-quick-links.php

Stats can be hidden/shown by clicking the icon top right on the pending or completed sales headers. See below:

If you wish you can have a custom message display for admin users above the homescreen graph/stats. See the notes in the following file: admin/templates/custom-user-message.php Messages can be customised per user.

The same or additional information may be provided by hovering your cursor over the image next to each heading in the admin area if applicable.
