As you progress with your router, expanding and experimenting with the features will enhance your abilities and increase the scopeof work you can achieve. Using the fence as a guide is common practice but it can also be used for decorative features.
A good exercise is to use it for parallel groove work. With only a few passes and adjustments it allows you to make simple but effective faux Shaker style panels or planked effects with just a V groove or smallcore box cutter. Experimenting with different cutters and fence positions will easily allow new designs and styles to your work.
