To add Admin Tools, here are the step-by-step instructions:
1. Open settings, go to Customize Start Menu tab.
2. Scroll all the way down in right column, locate "Custom Command", double click to add it or drag it. Position it up/down where you want it.
3. Now double click "CustomItem" in left column, from the "Link" field dropdown, choose Administrative Tools.
4. Assign an icon if you want, label, tooltip - all optional. Set options as you want like "Don't Expand" if you want to show it as a Link, not an expanding menu. Click OK twice.
