Advanced mode gives you access to more of Top Dog's settings without being confusing.

Top Dog operates in one of three modes: "Lite", "Advanced" or "Power User".
To change modes simply click on the appropriate button at the top of the Status tab.

Follow the links on the left which explain what each tab does when in Advanced mode.

Lite mode is designed for people who want the job done with the minimal amount of fuss.
Advanced mode is for people who want a bit more control.
Power User mode allows you to set specific ports, create custom rules, etc...
